Deprecated since 2026-04-21Use CategoryTheory.Mod.scalarRestriction_hom instead.

∀ {C : Type u₁} [inst : CategoryTheory.Category.{v₁, u₁} C] [inst_1 : CategoryTheory.MonoidalCategory C] {D : Type u₂}
  [inst_2 : CategoryTheory.Category.{v₂, u₂} D] [inst_3 : CategoryTheory.MonoidalCategory.MonoidalLeftAction C D]
  {A B : C} [inst_4 : CategoryTheory.MonObj A] [inst_5 : CategoryTheory.MonObj B] (f : A ⟶ B)
  [inst_6 : CategoryTheory.IsMonHom f] (M N : D) [inst_7 : CategoryTheory.ModObj B M]
  [inst_8 : CategoryTheory.ModObj B N] (g : M ⟶ N) [CategoryTheory.IsModHom B g], CategoryTheory.IsModHom A g

Alias of CategoryTheory.Mod.scalarRestriction_hom. If g : M ⟶ N is a B-linear morphism of B-modules, then it induces an A-linear morphism when M and N have an A-module structure obtained by restricting scalars along a monoid morphism A ⟶ B.
