Free products and rescalings involving non-separable abelian von Neumann algebras

Ken Dykema, Junchen Zhao

For a self-symmetric tracial von Neumann algebra $A$ , we study rescalings of $A^{* n} * L F_{r}$ for $n \in N$ and $r \in (1, \infty]$ and use them to obtain an inter…

Some non-spectral DT-operators in finite von Neumann algebras

Ken Dykema, Amudhan Krishnaswamy-Usha

Given a DT-operator $Z$ whose Brown measure is radially symmetric and has a certain concentration property, it is shown that $Z$ is not spectral in the sense of Dunford. This is ac…
