On cohomology of quasitoric manifolds over a vertex cut of a finite product of simplices

Date: 24.11.2023 (coming Friday). 
Time and Venue: 16:30–17:30 Ramanujan Hall at TC.
Speaker: Dr. Soumen Sarkar, IIT Madras
Title: On cohomology of quasitoric manifolds over a vertex cut of a finite product of simplices
Abstract: In this talk, I’ll classify the characteristic matrices associated to quasitoric manifolds over a vertex cut of a finite product of simplices satisfying a `sign condition’. I’ll discuss the integral cohomology rings of these quasitoric manifolds with possibly minimal generators and show several relations among the products of these generators.

Then, I’ll classify integral cohomology rings (up to isomorphism as graded rings) of the quasitoric manifolds over the vertex cut of a finite product of simplices. This is a joint work with Subhankar Sau.
