Title: On fundamental groups of tensor product II1 factors
Time/Date: 4:45-6:15, Monday, May 29, 2017.
Abstract: We study a stronger notion of primeness for II1 factors, which was introduced in my previous work. Using this, we prove that if G and H are groups which are realized as fundamental groups of II1 factors, then so are groups GH and G \cap H.
