On $* -$ Reverse Derivable Maps

Gurninder S. Sandhu, Bruno L. M. Ferreira, D. Kumar

Let $R$ be a ring with involution containing a nontrivial symmetric idempotent element $e$ . Let $δ : R \to R$ be a mapping such that $δ (ab) = δ (b) a^{*} + b^{*} δ (a)$ for all…

Additivity of Reverse Derivable Maps

Gurninder Singh Sandhu, Deepak Kumar

Let $R$ be any ring containing a non-tivial idempotent element $e$ . Let $ℑ : R \to R$ be a mapping such that $ℑ (ab) = ℑ (b) a + b ℑ (a)$ for all $a, b \in R$ . In this note, our…
