The only file importing
algebra/group_ring_action/invariant
wasalgebra/hom/group_action
. This means that the material needing both files can safely be moved fromhom/group_action
togroup_ring_action/invariant
, while only decreasing the imports of anything else in the hierarchy.This is worth doing since
group_ring_action/invariant
has another relatively heavy import (ring_theory/subring/pointwise
). After this rearrangement,hom/group_action
should be ready to port.
