Decomposibility and norm convergence properties in finite von Neumann algebras
Ken Dykema, Joseph Noles, Dmitriy Zanin
We study Schur-type upper triangular forms for elements, T, of von Neumann algebras equipped with faithful, normal, tracial states. These were introduced in a paper of Dykema, Suko…
Non-closure of the set of quantum correlations via graphs
Ken Dykema, Vern I. Paulsen, Jitendra Prakash
We prove that the set of quantum correlations for a bipartite system of 5 inputs and 2 outputs is not closed. Our proof relies on computing the correlation functions of a graph, wh…
The Delta Game
Ken Dykema, Vern I. Paulsen, Jitendra Prakash
We introduce a game related to the game and analyze a constrained value function for this game over various families of synchronous quantum probability densities.
Nilpotent elements of operator ideals as single commutators
Ken Dykema, Amudhan Krishnaswamy-Usha
For an arbitrary operator ideal I, every nilpotent element of I is a single commutator of operators from I^t, for an exponent t that depends on the degree of nilpotency.
Simultaneous upper triangular forms for commuting operators in a finite von Neumann algebra
Ian Charlesworth, Ken Dykema, Fedor Sukochev +1
The joint Brown measure and joint Haagerup--Schultz projections for tuples of commuting operators in a von Neumann algebra equipped with a faithful tracial state are investigated,…
