Research Description

My research involves that area of Algebra where Ring Theory, Commutative Algebra and Algebraic Geometry overlap. The main focus is the Brauer group of a commutative ring, which classifies the Azumaya algebras. The rings that arise are rings of functions defined on algebraic varieties. This study employs many methods from all areas of Algebra. There are essential connections with the theory of separable algebras, Morita theory, the theory of faithfully flat descent, Galois theory, cohomology, derivations, differentials, reflexive lattices, maximal orders and class groups.

Scholarly Activities

Being a mathematical fanatic, I never stop working. I'm doing math 24 hours a day, 7 days a week.
