Relative amenability of Banach algebras
Hoger Ghahramani, Wania Khodakarami, Esmaeil Feizi
Let A be a Banach algebra and I be a closed ideal of A. We say that A is amenable relative to I, if A/I is an amenable Banach algebra. We study the relative amenability of Banach 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…

Automatic continuity of Some linear mappings from certain products of Banach algebras
Hamid Farhadi, Eghbal Ghaderi, Hoger Ghahramani
Let and be Banach algebras and be a nonzero character on . Then the \textit{Lau product Banach algebra} $\mathcal{A}\times_θ\mathcal{U}…
