The classification problem for finitely generated operator systems and spaces
Martín Argerami, Samuel Coskey, Mehrdad Kalantar +3
The classification of separable operator spaces and systems is commonly believed to be intractable. We analyze this belief from the point of view of Borel complexity theory. On one…
C*-simplicity and the unique trace property for discrete groups
Emmanuel Breuillard, Mehrdad Kalantar, Matthew Kennedy +1
A discrete group is said to be C*-simple if its reduced C*-algebra is simple, and is said to have the unique trace property if its reduced C*-algebra has a unique tracial state. A…
Thompson's theorem for II_1 factors
Matthew Kennedy, Paul Skoufranis
A theorem of Thompson provides a non-self-adjoint variant of the classical Schur-Horn theorem by characterizing the possible diagonal values of a matrix with given singular values.…
Boundaries of reduced C*-algebras of discrete groups
Mehrdad Kalantar, Matthew Kennedy
For a discrete group G, we consider the minimal C*-subalgebra of that arises as the image of a unital positive G-equivariant projection. This algebra always exists…
