Jordan Higher All-Derivable Points in Nest Algebras

Nannan Zhen, Jun Zhu

Let $N$ be a non-trivial and complete nest on a Hilbert space $H$ . Suppose $d = {d_{n} : n \in N}$ is a group of linear mappings from Alg $N$ into itself. We say tha…

Jordan product determined points in matrix algebras

Yang Wenlei, Zhu Jun

Let $M_{n} (R)$ be the algebra of all $n \times n$ matrices over a unital commutative ring $R$ with 6 invertible. We say that $A \in M_{n} (R)$ is a Jordan product determined point if for…

Jordan higher all-derivable points in triangular algebras

Jun Zhu, Jinping Zhao

Let $T$ be a triangular algebra. We say that $D = {D_{n} : n \in N} \subseteq L (T)$ is a Jordan higher derivable mapping at $G$ if $D_{n}(ST+TS)=\sum_{i+j=n}(D…

Characterizations of all-derivable points in nest algebras

Jun Zhu, Sha Zhao

Let $A$ be an operator algebra on a Hilbert space. We say that an element $G \in A$ is an all-derivable point of $A$ if every derivable linear mapp…
