U. Haifa Topology & Geometry seminar: Wednesday, Jan. 15, 2025. Speaker: Irakli Patchkoria (Aberdeen). Title: “Chromatic congruences and Bernoulli numbers”.
For every n and a fixed prime p, we construct a new congruence for the orbifold Euler characteristic of a group which we call the chromatic congruence at the height n. Here the word “chromatic” refers to the chromatic stable…

Colloquium: Tuesday Nov. 26, 2024. Speaker: Michael Chapman, (NYU). Title: “Subgroup Tests and the Aldous-Lyons Conjecture”.
Zoom recording Abstract:The Aldous-Lyons conjecture from probability theory states that every (unimodular) infinite graph can be (Benjamini-Schramm) approximated by finite graphs. This conjecture is an analogue of other influential conjectures in mathematics concerning how well certain infinite objects can be…

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’”.
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…
