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 $\text{1}$ and $ \M $ be a unital Banach left $ \A $-module. let $ δ: \A \rightarrow \M$ be a continuous linear map with the property that…
