Connes' rigidity conjecture for groups with infinite center

We propose a natural version of Connes' Rigidity Conjecture (1982) that involves property (T) groups with infinite center. Using methods at the rich intersection between von Neumann algebras and geometric group theory, we identify several instances where this conjecture holds. This is joint work with Ionut Chifan, Denis Osin and Hui Tan.
