Definition:Right Ring Action Defined by Ring Antirepresentation

Definition

Let $R$ be a ring.

Let $M$ be an abelian group.

Let $\rho: R \to \map {\operatorname {End} } M$ be a ring antirepresentation.

The associated right ring action is the right linear ring action:

$M \times R \to M$:

$\tuple {m, r} \mapsto \map \rho r \paren m$
