Joint spectrum shrinking maps on projections

Wenhua Qian, Dandan Xiao, Tanghong Tao +2

Let $H$ be a finite dimensional complex Hilbert space with dimension $n \geq 3$ and $P (H)$ the set of projections on $H$ . Let $φ: \mathcal P(\mat…

Characterizations of centralizable mappings on algebras of locally measurable operators

Guangyu An, Jun He, Jiankui Li

A linear mapping $ϕ$ from an algebra $A$ into its bimodule $M$ is called a centralizable mapping at $G \in A$ if $ϕ (A B) = ϕ (A) B = A ϕ (B)$ for each $A$ and $B$ …

Wigner-Type Theorem on transition probability preserving maps in semifinite factors

Wenhua Qian, Liguang Wang, Wenming Wu +1

The Wigner's theorem, which is one of the cornerstones of the mathematical formulation of quantum mechanics, asserts that every symmetry of quantum system is unitary or anti-unitar…

Characterizations of centralizers and derivations on some algebras

Jun He, Jiankui Li, Wenhua Qian

A linear mapping $ϕ$ on an algebra $A$ is called a centralizable mapping at $G \in A$ if $ϕ (A B) = ϕ (A) B = A ϕ (B)$ for each $A$ and $B$ in $A$ with $A B = G$ , an…

Derivations and 2-local derivations on matrix algebras over commutative algebras

Wenbo Huang, Jiankui Li, Wenhua Qian

We characterize derivations and 2-local derivations from $M_{n} (A)$ into $M_{n} (M)$ , $n \geq 2$ , where $A$ is a unital algebra over $C$ and $\…

Similarity degree of type II $_{1}$ von Neumann algebras with Property $Γ$

Don Hadwin, Wenhua Qian, Junhao Shen

In this paper, we discuss some equivalent definitions of Property $Γ$ for a type II $_{1}$ von Neumann algebra. Using these equivalent definitions, we prove that the Pisier's similari…

Similarity degree of a class of C $^{*}$ -algebras

Wenhua Qian, Junhao Shen

Suppose that $M$ is a countably decomposable type II $_{1}$ von Neumann algebra and $A$ is a separable, non-nuclear, unital C $^{*}$ -algebra. We show that, if $\mathcal…

Hochschild cohomology of type II $_{1}$ von Neumann algebras with Property $Γ$

Wenhua Qian, Junhao Shen

In this paper, Property $Γ$ for a type II $_{1}$ von Neumann algebra is introduced as a generalization of Murray and von Neumann's Property $Γ$ for a type II $_{1}$ factor. The main…
