2n-Weak module amenability of semigroup algebras
Hoger Ghahramani
Let be an inverse semigroup with the set of idempotents . We prove that the semigroup algebra is always -weakly module amenable as an -module,…
Characterizations of left derivable maps at non-trivial idempotents on nest algebras
Hoger Ghahramani
Let be a nest algebra associated with the nest on a (real or complex) Banach space $\X$. Suppose that there exists a non-trivial idempotent $P\in A…
Characterizing Jordan centralizers and Jordan generalized derivations on triangular rings through zero products
Hoger Ghahramani
Let $\T$ be a -torsion free triangular ring and let $φ:\T\rightarrow \T$ be an additive map. We prove that if $\A φ(\B)+φ(\B)\A=0$ whenever $\A,\B\in \T$ are such that $\A\B=\B\…
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 and $ \M $ be a unital Banach left $ \A $-module. let $ δ: \A \rightarrow \M$ be a continuous linear map with the property that…
On derivations and Jordan derivations through zero products
Hoger Ghahramani
Let $\A$ be a unital complex (Banach) algebra and $\M$ be a unital (Banach) $\A$-bimodule. The main results describe (continuous) derivations or Jordan derivations $D:\A\rightarrow…
Jordan derivations on block upper triangular matrix algebras
Hoger Ghahramani
We provide that any Jordan derivation from the block upper triangular matrix algebra $\T = \T(n_{1},n_{2}, \cdots, n_{k})\subseteq M_{n}(\mathbb{\C})$ into a -torsion free unita…
