Research in Mathematics

The Mathematics Group at Harish-chandra Research Institute Conducts Research in Algebra, Analysis, Geometry and Topology, and Number Theory. The Group Consists of Faculty Members, Visiting Scientists, Postdoctoral Fellows, and Graduate Students. An Accompanying Document Contains More Information on the Research Interests of Individual Members of the Group.

Algebra and Algebraic Geometry:

Group theory (Manoj Kumar Yadav)

Abstract Group Theory: Automorphisms, Conjugacy Classes, Commutator Word Map, and Low Dimensional     Cohomology; Braces and Skew Braces; Yang-baxter Equation.
