U. Haifa Topology & Geometry seminar: Wednesday, Nov. 27, 2024. Speaker: Giuseppe Leoncini (Università degli Studi di Milano Statale). Title: “Universal homotopy theories in the enriched context’”.

Author: November 27, 2024

I will put forward a possible generalization of Dugger’s theorem on universal homotopy theories, in enriched homotopy theory, following previous work of Dugger and Shipley for the case of enrichment over Abelian groups. I will discuss what can be done…

U. Haifa Topology & Geometry seminar: Tuesday, Apr. 9, 2024. Speaker: Kaif Hilman (Bonn). Title: “Equivariant Poincare duality for finite groups and fixed points methods”.

Author: April 9, 2024

In this talk, I will introduce the notion of Poincar´e duality spaces in the equivariantsetting for finite groups and discuss an approach relating equivariant Poincar´e duality withPoincar´e duality on the fixed points. Time permitting, I will also indicate how one…

U. Haifa Topology & Geometry seminar: Tuesday, Mar. 5, 2024. Speaker: Surojit Ghosh (IIT Roorkee). Title: “Higher homotopy invariants of diagrams of chain complexes”.

Author: March 5, 2024

While encoding the homotopy invariants in a model category, one approach (due to Heller and Grothendieck) is to determine certain higher invariants in the homotopy categories of all small diagram categories. In this talk, we provide an explicit approach to…
