Abstract

This is a continuation of our previous paper studying the structure of Cartan subalgebras of von Neumann factors of type II₁ -We provide more examples of II₁ factors having either zero, one, or several Cartan subalgebras. We also prove a rigidity result for some group measure space II₁ factors.
