Title: Computation of Persistent Homology Using the Delaunay-Rips Complex: An Efficient Family of Simplicial Complexes for Topological Data Analysis 

Abstract: Topological Data Analysis is an emerging area rooted in theories from Algebraic Topology, which enables researchers to extract discriminating geometric and topological features from data. We give an overview of some of the popular methods of extracting features from point-cloud data, which first requires one to construct a 1-parameter family of spaces on the data using the geometry of the cloud. We demonstrate their benefits and shortcomings and introduce a new, more efficient construction that we name the Delaunay-Rips Complex. We justify conditions on the data that guarantee stability of our method when computing persistent homology. Aided by intuitive examples, we also provide an empirical run-time comparison of the two existing methods with our new algorithm on the computation of the persistence diagrams of some synthetic data sets.

MS Exam (Presentation): Matthew Trang  

Title: Modules of Kahler Differentials 

Abstract: In algebra, the notion of Kahler differentials introduced by Erich Kahler in the 1930s gives us a way to adapt the notion of differential forms to arbitrary commutative rings. It has not only been used in commutative algebra, but also in algebraic geometry where the methods from calculus fail to apply. Besides, the module of Kahler differentials is a powerful tool for studying separable algebras over commutative rings and it is also applied to prove some criteria for regularity of local rings. In this presentation, we will give an introduction to derivations, the module of Kahler differentials, its universal mapping property as well as some of its basic properties. To finish the talk, we will provide a differential criterion for regularity of local rings, which geometrically gives us a way to determine if a variety is nonsingular or singular at some certain point.

Title: The Three Subspace Problem

Abstract: Given a vector space and three subspaces, we are interested in the classification of all configurations up to an automorphism of the ambient space. Although this problem can be stated solely in terms of Linear Algebra, we will be using tools from Representation Theory to tackle this problem.

Title: Lemniscate Trees of Random Polynomials and Asymptotic Enumeration of Morse Functions on the 2-Sphere

Abstract: We'll consider two problems: first we'll investigate the nesting structure of lemniscate configurations associated to complex polynomials, and in the second part of the talk we'll determine the asymptotic for the number of geometric equivalence classes of Morse functions on the 2-sphere. Both the lemniscate configurations and the equivalence classes of Morse functions are enumerated by classes of labeled trees, and both problems are amenable to the methods of analytic combinatorics. Along the way we'll introduce some of the basic techniques in this fascinating area.

Title: Statistical Arbitrage Strategy in Multi-Asset Market Using Time Series Analysis 

Abstract: The statistical arbitrage strategy is widely used in financial investment. Almost all of current statistical arbitrage strategies focus on the price difference (spread) between two similar assets in the same asset class and exploit the mean reversion of spreads, i.e. pairs trading. This study extends the strategy to multiple assets in the multi-asset market and derives a mean-reverting portfolio by optimizing multiple mean-reversion criteria (the method is called PGP). By performing an empirical analysis, this study shows the profitability of the new strategy.

Title: Bezout's Theorem 

Abstract: A major topic of Algebraic Geometry is the study of zero sets of families of polynomials. One of the " Great Theorems " in Algebraic Geometry is Bezout's Theorem, which deals with the intersection of curves in Projective Planes. The Theorem States: Let F and G are two projective plane curves with no "common component " , where the degrees of F and G are m and n respectively. Then the number of points of intersection of F and G is mn. In this presentation, I am going to define the concept of Projective Varieties Intersection Numbers and then to prove Bezout's Theorem.

Title: Predicting Tropical Cyclone Intensity from Geosynchronous Satellite Images Using Deep Neural Networks 

Advisor: Dr. Francis Motta 

Abstract

Tropical cyclones are among the most devastating natural disasters for human beings and the natural and manmade assets in some parts of the United States. Therefore, estimating the current and future intensity of these powerful storms is crucial to protect life and property. National Hurricane Center (NHC) is one of the professional tropical storm intensity forecasting center located in Miami, Florida. NHC and NOAA (National Oceanic and Atmospheric Administration) are responsible for the tracking, monitoring, predicting cyclone formation and evolution around the United States. My study mainly focuses on estimate tropical cyclone intensity using Geostationary Operational Environmental Satellites (GOES) images, which have been capturing high spatial resolution images (1-4km2) of most of the globe every 30 minutes for decades.

Title: Some Fixed-Point Theorems and Their Applications in Analysis 

Abstract: The fixed points of a map are important objects in analysis, and their existence gives us a simple yet powerful tool to obtain relevant results. In our set up, we prove some well-known results, as the completeness of the space C[a,b] under the d-sup metric, which complemented with fixed-point theorems leads to important conclusions. Then, we explore some fixed-point theorems, one of them Banach’s fixed point theorem, and their implications in Analysis; such as Picard’s existence and uniqueness theorem for a first order initial value problem, as well as second order.

Title: Krull’s Principal Ideal Theorem and Systems of Parameters for a Local Ring 

Abstract: In this presentation we prove Krull’s principal ideal theorem, one of the workhorses of commutative algebra. This theorem can be generalized to ideals that are not principal, and the result is often called Krull's height theorem, which is a cornerstone of the dimension theory of Noetherian rings. It states that any minimal prime ideal of an ideal generated by n elements in a Noetherian ring has height at most n. As corollaries, we obtain the existence of systems of parameters of Noetherian local rings, and the fact that every Noetherian local ring has finite dimension. Along the way, important lemmas are proved, such as Nakayama’s lemma.

Title: Existence of Solutions of Initial Value Problems

Abstract: In the beginning of the study of differential equations, the focus is on finding explicit solutions, focusing on solving the underlying physical problems. Then immediately after multiple questions arises, such as – if a starting point for a solution of differential equations is given, does the solution always exist? If it exists, how long does it exist and is there only one such solution? In this presentation, we are going to answer some of the above questions. We are studying this because its importance grew more and more over time then the beginning of the nineteenth century when it was first introduced by Cauchy. It is useful significantly to delay equations, functional differential equations, partial differential equations or stochastic differential equations and finite- and infinite dimensional dynamical systems.

Mathematical modeling is a powerful tool to study and analyze the disease dynamics prevalent in the community. This thesis studies the dynamics of two time since infection structured vector borne models with the direct transmission. We have included disease induced death rate in the first model to from the second model. The aim of this thesis is to analyze whether these two models have same or different disease dynamics. An explicit expression for the reproduction number denoted by R0 is derived. Dynamical analysis reveals the forward bifurcation in the first model. That is when the threshold value R0 < 1, disease free equilibrium is stable both locally and globally implying disease dies out from the population. When R0 > 1 existence of unique endemic equilibrium is locally asymptotically stable.

For the second model, analysis of the existence and stability of equilibria reveals the existence of backward bifurcation i.e. where the disease-free equilibrium coexists with the endemic equilibrium when the reproduction number R02 is less than unity. This aspect shows that in order to control vector borne disease, it is not sufficient to have reproduction number less than unity although necessary. Thus, the infection can persist in the population even if the reproduction number is less than unity. Numerical simulation is presented to see the bifurcation behavior in the model. By taking the reproduction number as the bifurcation parameter, we find the system undergoes backward bifurcation at R02 = 1. Thus, the model has backward bifurcation and have two positive endemic equilibrium when R02 < 1 and unique positive endemic equilibrium whenever R02 > 1. Stability analysis shows that disease free equilibrium is locally asymptotically stable when R02 < 1 and unstable when R02 > 1. When R02 < 1, lower endemic equilibrium in backward bifurcation is locally stable

Title: Continuation in Dynamics

Authors: K. Alex Dowling, William Kalies, Robert Vandervorst

Abstract: In this work, we describe continuation of structure in families of dynamical systems using category, sheaf, and lattice algebras. We start by framing many well-known concepts in dynamics, such as attractors or invariant sets, as functors on a category of dynamical systems into a category of lattices or posets. Then, we construct sheaves from such functors, which encode data about the continuation of structure as system parameters vary. Similarly, we build morphisms for these sheaves from natural transformations. This framework is then applied to a variety of lattice algebras associated to dynamical systems, whose algebraic properties carry over to their respective sheaves. Furthermore, we show the cohomology groups of these sheaves contain information about bifurcations of the system. We give several examples relating the structure of these groups to information about the type of bifurcation.

Title: Survival Analysis with Cox Proportional Hazard Deep Learning Neural Networks

Abstract: Survival models are used to explore and understand the relationship between individuals’ covariates (e.g. clinical and genetic features) and the effectiveness of various treatment options. There are two types of models:

1. Standard survival models: Cox proportional hazards model.

2. Nonlinear survival models: Neural network and survival forest.

The main problem of standard models is that they need extensive feature engineering, prior (medical) knowledge, or pre-assumptions to model treatment interaction at individual level, while nonlinear can inherently model these high-level interaction terms. One of the conspicuous nonlinear models is DeepSurv: A Cox proportional hazards deep neural network.

In this work, through the results of training DeepSurv on the simulated and real survival data, we will show that the performance of DeepSurv in modeling highly complex relationships between an individual’s covariates and their risk of failure is as well as or better than others. The capabilities of DeepSurv in the prediction and modeling can enable researchers to use deep neural network as a tool in their exploration, understanding, and prediction of the effects of a individuals' characteristics on their risk of failure.

Title: Algorithms in Lattice-Based Cryptanalysis

Co-Advisors: Dr. Shi Bai and Dr. Rainer Steinwandt

Abstract:

An adversary armed with a quantum computer has algorithms at their disposal, which are capable of breaking our current methods of encryption. Even with the birth of post-quantum cryptography, some of the best cryptanalytic algorithms are still quantum. This thesis discusses the cryptanalysis of lattice-based cryptography using classical and quantum algorithms. Several experiments are conducted concerning the efficacy of lattice reduction algorithms, BKZ and LLL. In particular, the difficulty of solving Learning With Errors is assessed by reducing the problem to an instance of the Unique Shortest Vector Problem. The results are used to predict the behavior these algorithms may have on actual cryptographic schemes with security based on hard lattice problems. Lattice reduction algorithms may require several floating-point operations including multiplication. In this thesis, I consider the resource requirements of a quantum circuit designed to simulate floating-point multiplication with high precision.

FAU's Student Chapter of the American Women IN Mathematics (AWM) presents:
'Going Virtual' Live Q & A Tea 

The FAU AWM Graduate Student Chapter has considered the drastic changes that COVID-19 has had on the education as well as professional standards. The requirements to transit to an all-virtual learning environment can be inconvenient even for non-beginners. This live question and answer session is to raise solutions and have an open discussion on the various resources known and used by experts to alleviate the burden on students and academic professionals working within the mathematical sciences to adjust to these changes. We hope to enhance a smoother transition to virtual learning environments and that the information will be vital for everyone involved.

Tuesday Tea's are an on-going initiative that the FAU AWM Chapter has practiced in order to promote functional and meaningful conversations within mathematics and the STEM communities, to continue building professional and social networks amongst student-to-student relations, academic faculty, as well as industry professionals.

This event is open to anyone interested in mathematics at FAU and neighboring institutions! Please sign up so that we can contact you with relevant information in the future. We would love to connect with you!

Title: DYNAMIC AND CONTROL OF AUTOIMMUNE DISORDER UNDER RADIATION

Abstract:  Autoimmune diseases can be developed by exposure to radiation. Ionizing radiation modifies the immune system and diminishing its normal ability to fight diseases.  The extents of the modifications depend on the dose rate and duration of radiation exposure.  This work employs mathematical simulations of autoimmune process dynamics under irradiation. The mathematical model employed in this work consists of four non-linear differential equations.  The variables used in the modeling are the concentration of target cells of the tissue, concentration of cytotoxic T-lymphocytes, the concentration of tissue-specific antigen, and the concentration of T-suppressor cortical thymus.

Title: TDALabs: (Some of) TDA's Greatest Hits in Interactive Python
Abstract: Abstract: TDA software is becoming more mainstream and accessible to both mathematicians in the field and to data scientists at large. Recently, I worked as part of a small team of open source software developers to create a Python library known as scikit-tda (https://scikit-tda.org/). In addition to using this library in myriad research applications, I have also been developing a compendium of examples for pedagogical purposes, some of which are in a repository I call "TDALabs" (https://github.com/ctralie/TDALabs). In this talk, I will interactively go through a number of these examples, including a demo of the stability theorem, sliding windows in time series and video, the natural space of image patches, diffusion maps and TDA, lower star image filtrations for cell segmentation in images, mesh reconstruction via alpha shapes, and isometry blind 3D shape clustering. It is the hope that people will be inspired to use these materials in their own courses and workshops, and it is also the hope that some will help me build on them and contribute additional concise examples that showcase their work. Pull requests are welcome!

Abstract: The equations of motion for gravitating bodies have singularities when any two of the bodies occupy the same point in space, i.e. when there is a collision.  It is well known, but still quite interesting, that one can make sense of orbits that ``go through'' collisions by a process called regularization.  I'll introduce the idea of regularization and illustrate its use in some numerical calculations

Title: Oriented Matroids and Combinatorial Neural Codes.
Abstract: A combinatorial neural code is convex if it arises as the intersection pattern of convex open subsets of Euclidean space. We relate the emerging theory of convex neural codes to the established theory of oriented matroids, in both a category-theoretic sense and with respect to feasibility and complexity. By way of this connection, we prove that all convex codes are related to some representable oriented matroid, and we show that deciding whether a neural code is convex is NP-hard.

Title: Stability Analysis of the SIR model
Abstract:  The SIR model is one way that we can analyze how the spread of a disease effects a population overtime.  In this model, the spread of a disease divides our population into 3 non-intersecting classes: susceptible, infected, and recovered.  By studying the dynamics of this system, we are able to predict how the disease will behave in the population. We are interested in the stability of the equilibria points which will help us decide whether a disease will die out, or if it will stabilize itself.

FAU's Student Chapter of the AWM Care To BEE Event

Dr. Nina Fefferman will be joining us live on Webex for a problem-solving session based on topics from a pre-recorded webinar from NIMBioS,  "The Role of Applied Math in Real-time Pandemic Response How Basic Disease Models Work"

Dr. Nina Fefferman is a mathematical biologist with a long history of work on biosecurity and pandemic preparedness and response. She has consulted in this area for state and federal agencies and departments on threats including TB, Ebola, Zika virus, H1N1 2009, and many others, now including COVID-19. She is a professor in the Departments of Mathematics and Ecology & Evolutionary Biology at the University of Tennessee, Knoxville. Dr. Fefferman directs the Mathematical Modeling Center at the National Institute for Mathematical and Biological Synthesis.

Abstract: It's not normally instantly obvious what mathematicians do. It's also not normal to be able to use middle-school math to help try to save the world. Right now, things are not normal. Join us for "The role of applied math in real-time pandemic response: How basic disease models work" for a presentation about how very simple, middle-school math (and much fancier versions of the same thing) can help us fight COVID-19.

Be sure to register online. This conference is open to anyone interested in mathematics at FAU and neighboring institutions! Please sign up so that we can contact you with relevant information. Also, if you would like to provide a mailing address, we will be sending out promotional items (note this is optional).
