On $(\delta ,f)$-derivations and Jordan $(\delta ,f)$-derivations on modules

Gusti Ayu Dwi Yanti, Indah Emilia Wijayanti

Let $R$ be a ring with identity, $M,N$ right modules over $R$. An additive mapping $\delta$ from $R$ to $R$ is called derivation on ring $R$ if it satisfies the Leibniz condition. If $δ…
