Mathlib.Algebra.GroupRingAction.Subobjects

# Instances of MulSemiringAction for subobjects #

These are defined in this file as Semirings are not available yet where Submonoid and Subgroup are defined.

Instances for Subsemiring and Subring are provided next to the other scalar actions instances for those subobjects.

instance Submonoid.mulSemiringAction {M : Type u_1} {R : Type u_2} [inst : ] [inst : ] [inst : ] (H : ) :
MulSemiringAction { x // x H } R

A stronger version of Submonoid.distribMulAction.
