This week, Thursday at 10:00, U. Haifa Topology & Geometry seminar on November 21, 2019

Geometry & Topology Seminar

Speaker: Dimitar Kodjabachev (University of Haifa)

Topic: Equivariant Gorenstein Duality

Place:    Room 614 in the Science & Education Building

Time:   10:00

Date:  Thursday, November 21, 2019


The notion of Gorenstein duality introduced by Dwyer, Greenlees and Iyengar
allows one to view a number of dualities such as Poincaré duality for manifolds,
Gorenstein duality for commutative rings and Benson-Carlson duality for
cohomology rings of finite groups as instances of a single phenomenon. In this
talk I will set up an equivariant generalization of the framework and I will
look at examples coming from derived algebraic geometry, namely – the ring
spectra of topological modular forms with level structure.
