Homological invariants of group Banach algebras of discrete groups
23 novembre 2023 @ 14:15 – 15:15 – Several conjectures about « assembly maps » in $K$-theory (Baum-Connes Conjecture) and surgery theory (Borel Conjecture) rank among the most significant open problems about discrete groups. In this talk we will present some recent progress on a similar conjecture about the assembly map in local cyclic homology for discrete, cocompact isometry groups of $CAT(0)$-spaces.
