U. Haifa Topology & Geometry seminar: Wednesday, Apr. 2, 2025. Speaker: Tom Bachmann (Mainz). Title: “Coalgebras in p-adic homotopy theory”.

Author: April 3, 2025

I will report on joint work with Robert Burklund in which we remove finiteness assumptions from a theorem of Mandell. Specifically, we show that the canonical functor from p-adic,nilpotent spaces to (E∞-) coalgebras over F¯p is fully faithful.

U. Haifa Topology & Geometry seminar: Wednesday, Mar. 19, 2025. Speaker: Marina Prokhorova (Haifa). Title: “Index theory for unbounded Fredholm operators”.

Author: March 19, 2025

A linear operator on a Hilbert space is called Fredholm if its kernel and cokernel are finitedimensional. As was shown in classical works of Atiyah, J¨anich, and Singer, the space of bounded Fredholm operators represents even K-theory; its subspace consisting…
