“GJS C*-algebras”

Guionnet-Jones-Shlyakhtenko (GJS) gave a diagrammatic proof of a
result of Popa which reconstructs a subfactor from a subfactor planar
algebra. In the process, certain canonical graded *-algebras with
traces appear. In the GJS papers, they show that the von Neumann
algebras generated by the graded algebras are interpolated free group
factors. I will talk about current joint work with Hartglass which
examines the C*-algebras generated by the graded algebras.
