Property A vs. coarse embedding via graphs
Wednesday the 30th of October, 2024, 13:00, Room 2.2.D08
Since the creation of the coarse Baum-Connes conjecture there has been great interest in finding metric spaces which coarsely embed into Hilbert space. Of particular interest is when a metric space coarsely embeds into a Hilbert space yet does not possess G. Yu's 'property A'.A useful tool for coarsely embedding a graph $X$ into Hilbert space is the wall metric, $d_w$, which differs from the standard graph metric $d$. We will discuss an example of a metric space which coarsely embeds into Hilbert space and does not have property A and what we can say about $(X,d)$ based on results obtained from studying $(X,d_w)$.In this talk we will not assume prior familiarity with property A, coarse embeddings, and the wall metric.Link for online session (Active on request): https://eu.bbcollab.com/guest/d3ed81bffda3423692c5df53a2d584f4
