Approximate Equivalence in von Neumann Algebras
Qihui Li, Don Hadwin, Wenjing Liu
Suppose is a separable unital ASH C*-algebra, is a sigma-finite II factor von Neumann algebra, and ar…
Perturbations of self-adjoint operators in semifinite von Neumann algebras: Kato-Rosenblum theorem
Qihui Li, Junhao Shen, Rui Shi +1
In the paper, we prove an analogue of the Kato-Rosenblum theorem in a semifinite von Neumann algebra. Let be a countably decomposable, properly infinite, semifinite v…
A generalization of the Voiculescu theorem for normal operators in semifinite von Neumann algebras
Qihui Li, Junhao Shen, Rui Shi
In this paper, we provide a generalized version of the Voiculescu theorem for normal operators by showing that, in a von Neumann algebra with separable pre-dual and a faithful norm…
Topological Orbit Dimension of MF -algebras
Qihui Li, Don Hadwin, Weihua Li +1
This paper is a continuation of our work on D. Voiculescu's topological free entropy dimension in unital C*-algebras. In this paper we first prove the topological free entropy dime…
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…
