Title: Homogeneous quantum symmetries of finite spaces over the circle group
Speaker: Sutanu Roy (NISER, Bhubaneswar)
Date: 17 November 2021
Time: 4 pm
Venue: Microsoft Teams (online)

In 1998 Shuzhou Wang, in his pioneering work, introduced quantum symmetry groups of finite spaces motivated by a general question posed by Alain Connes: what is the quantum automorphism group of a space? By finite spaces, here we mean finite-dimensional C*-algebras. Wang’s results have initiated several fundamental developments in operator algebras, quantum groups and noncommutative geometry. Let us consider a generalised situation where we shall equip the finite spaces with a continuous action of the circle group. This talk aims to understand the object that captures the quantum symmetries of these systems and their applications.

The video of this talk is available on the IISc Math Department channel.
