On Lie n-centralizers, n-commuting linear maps and related mappings
Hoger Ghahramani
In this article, we consider several local conditions under which linear mappings on algebras act like Lie n-centralizers and we study these linear mappings, Lie n-centralizers and…
Left Ideal Preserving Maps on Triangular Algebras
Hoger Ghahramani
Let A be a unital algebra over a commutative unital ring R. We say that A is a SLIP algebra if every R-linear map on A that leaves invariant every left ideal of A is a left multipl…
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\…
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…
Characterizing Jordan derivations of matrix rings through zero products
Hoger Ghahramani
Let $\Mn$ be the ring of all matrices over a unital ring , let be a 2-torsion free unital $\Mn$-bimodule and let $D:\Mn\rightarrow \mathcal{…
