Ternary derivations of nest algebras

Hoger Ghahramani

Suppose that $X$ is a (real or complex) Banach space, $d im X \geq 2$ , and $N$ is a nest on $X$ , with each $N$ in $N$ is complemented in $X$ whenever $N_{-} = N$ . A…

Linear maps behaving like derivations or anti-derivations at orthogonal elements on C*-algebras

Behrooz Fadaee, Hoger Ghahramani

Let A be a C*-algebra and d from A into A** be a continuous linear map. We assume that d acts like derivation or anti-derivation at orthogonal elements for several types of orthogo…

Characterizations of left derivable maps at non-trivial idempotents on nest algebras

Hoger Ghahramani

Let $A l g N$ be a nest algebra associated with the nest $N$ on a (real or complex) Banach space $\X$. Suppose that there exists a non-trivial idempotent $P\in A…

Continuous linear maps on reflexive algebras behaving like Jordan left derivations at idempotent-product elements

B. Fadaee, H. Ghahramani

Let $\A$ be a Banach algebra with unity $1$ and $ \M $ be a unital Banach left $ \A $-module. let $ δ: \A \rightarrow \M$ be a continuous linear map with the property that…
