Thin II_1 factors with no Cartan subalgebras

Anna Sofie Krogager, Stefaan Vaes

It is a wide open problem to give an intrinsic criterion for a II_1 factor $M$ to admit a Cartan subalgebra $A$ . When $A \subset M$ is a Cartan subalgebra, the $A$ -bimodule $L^2(M)…

A class of II_1 factors with exactly two group measure space decompositions

Anna Sofie Krogager, Stefaan Vaes

We construct the first II_1 factors having exactly two group measure space decompositions up to unitary conjugacy. Also, for every positive integer $n$ , we construct a II_1 factor…
