DESCRIPTION:Title: <a href="https://researchseminars.org/talk/WienGAGT/6/"
 >Coxeter groups with connected Morse boundary</a>\nby Matt Cordes (ETH Zü
 rich) as part of Vienna Geometry and Analysis on Groups Seminar\n\n\nAbstr
 act\nThe Morse boundary is a quasi-isometry invariant that encodes the pos
 sible "hyperbolic" directions of a group. The topology of the Morse bounda
 ry can be challenging to understand\, even for simple examples. In this ta
 lk\, I will focus on a basic topological property: connectivity and on a w
 ell-studied class of CAT(0) groups: Coxeter groups. I will discuss a crite
 ria that guarantees that the Morse boundary of a Coxeter group is connecte
 d. In particular\, when we restrict to the right-angled case\, we get a fu
 ll characterization of right-angled Coxeter groups with connected Morse bo
 undary. This is joint work with Ivan Levcovitz.\n
