Artin Schelter regular algebras
Abstract: What are the noncommutative rings that are most analogous to polynomial rings? One class of such rings are the regular algebras first defined by Artin and Schelter in 1987. Since then such algebras have been extensively studied. We give a survey of these interesting examples and their associated projective geometry.

The space of closed subgroups
Abstract: Given a topological group G, one considers the space of its closed subgroups, called the Chabauty space. I will talk about the structure and features of this space, and show how various algebraic and topological properties of a group are expressed there.

Randomwalks in group extensions
Abstract: Basics of randomwalks in a finite group, superapproximation, and recent developments in this subject will be discussed. (More recent results are parts of my joint works with Srivatsa Srinivas.)

Tensor Categories
Abstract: Tensor categories have played an important role in areas as diverse as topology, mathematical physics, operator algebras and representation theory. This is an introductory talk. I will mostly talk about classification of tensor categories with given tensor product rules and module categories for certain important examples.
