A note on unital full amalgamated free products of quasi-diagonal C*-algebras
Qihui Li, Don Hadwin, Jiankui Li +2
In the paper, we consider the question whether a unital full amalgamated free product of quasidiagonal C*-algebras is quasidiagonal again. We give a sufficient condition such that…

Local derivations on Rings containing a von Neumann algebra and a question of Kadison
Don Hadwin, Jiankui Li, Qihui Li +1
We prove that if M is a von Neumann algebra whose abelian summand is discrete, then every local derivation on the algebra of all measurable operators affilated with M is a derivati…

On spectra and Brown's spectral measures of elements in free products of matrix algebras
Junsheng Fang, Don Hadwin, Xiujuan Ma
We compute spectra and Brown measures of some non self-adjoint operators in $(M_2(\cc), {1/2}Tr)*(M_2(\cc), {1/2}Tr)$, the reduced free product von Neumann algebra of $M_2(\cc)$ wi…
