II factors and equivalence relations with distinct fundamental groups
Jan Keersmaekers, An Speelman
We construct a group measure space II factor that has two non-conjugate Cartan subalgebras. We show that the fundamental group of the II factor is trivial, while the fundam…

A class of II_1 factors with many non conjugate Cartan subalgebras
An Speelman, Stefaan Vaes
We construct a class of II_1 factors M that admit unclassifiably many Cartan subalgebras in the sense that the equivalence relation of being conjugate by an automorphism of M is co…
