Mathlib.Algebra.Group.Subgroup.Pointwise

Pointwise instances on Subgroup and AddSubgroups #

This file provides the actions

which matches the action of Set.mulActionSet.

These actions are available in the Pointwise locale.

Implementation notes #

The pointwise section of this file is almost identical to the file Mathlib.Algebra.Group.Submonoid.Pointwise. Where possible, try to keep them in sync.
