Some functional identities characterizing two-sided centralizers and two-sided generalized derivations on triangular algebras
Amin Hosseini
Let T be a unital triangular algebra, let n > 1 be an integer, let gamma be an invertible element of Z(T), the center of T, and let Psi, Omega:\mathcal{T}\rightarrow \mathcal{T}$ b…

Continuity of conditional expectation in Orlicz spaces
A. Hosseini, Y. Estaremi
The continuity of conditional expectation on Orlicz spaces is investigated. Indeed, we provide some necessary and sufficient conditions on a sequence $\{\mathcal{A}_n\}_{n\in\mathb…

Strongly generalized derivations on C*-algebras
Amin Hosseini
Let and be two algebras, let be a -bimodule and let be a positive integer. A linear mapping $D_n:\mathcal{A} \rightarrow…
