| Description: | [DMS Topology & Geometry Seminar] Samik Basu (ISI Kolkata) -- Functions on the symmetric group and topological consequences |
| Date: | Thursday, Sep 26, 2024 |
| Time: | 2 p.m. - 3:30 p.m. |
| Venue: | 211, A P C Ray |
| Details: | The ring of Z-valued functions on the symmetric group \Sigma_k may be described in a simple manner using certain generators and relations. This is called the Varchenko-Gelfand ring.
