Title: "The median class for CAT(0) cubical complexes."
Speaker: Indira Chatterji (Université de Nice)
Abstract: I will discuss the median class, which is a bounded cohomology class on a group acting on a CAT(0) cube complex. I will explain how it detects fixed points on the cube complex or its boundary. This is based on joint work with T. Fernos and A. Iozzi.
