A description of amalgamated free products of finite von Neumann algebras over finite dimensional subalgebras
Ken Dykema
We show that a free product of a II_1-factor and a finite von Neumann algebra with amalgamation over a finite dimensional subalgebra is always a II_1-factor, and provide an algorit…
A non-convex asymptotic quantum Horn body
Benoit Collins, Ken Dykema
We prove by a counterexample that asymptotic quantum Horn bodies are not convex in general.
Sum--of--squares results for polynomials related to the Bessis--Moussa--Villani conjecture
Benoit Collins, Kenneth J. Dykema, Francisco Torres-Ayala
We show that the polynomial S_{m,k}(A,B), that is the sum of all words in noncommuting variables A and B having length m and exactly k letters equal to B, is not equal to a sum of…
Matrices of unitary moments
Ken Dykema, Kate Juschenko
We investigate certain matrices composed of mixed, second-order moments of unitaries. The unitaries are taken from C*-algebras with moments taken with respect to traces, or, altern…
