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…
A note on concentration functions on transformation groups
Mehrdad Kalantar, Mohammad S. M. Moakhar
In this note, we consider the concentration function problem for a continuous action of a locally compact group on a locally compact Hausdorff space . We prove a necessary a…
Realization of quantum group Poisson boundaries as crossed products
Mehrdad Kalantar, Matthias Neufang, Zhong-Jin Ruan
For a locally compact quantum group , consider the convolution action of a quantum probability measure on . As shown by Junge--Neufang--Ruan,…
On iterated powers of positive definite functions
Mehrdad Kalantar
We prove that if is an adapted positive definite function in the Fourier--Stieltjes algebra of a locally compact group with , then the iterated power…
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…
