∀ {M : Type u_1} [inst : CommMonoid M] {S : Submonoid M} {N : Type u_2} [inst_1 : CommMonoid N] {P : Type u_3}
  [inst_2 : CommMonoid P] (f : S.LocalizationMap N) {g : M →* P} {T : Submonoid P} (hy : ∀ (y : ↥S), g ↑y ∈ T)
  {Q : Type u_4} [inst_3 : CommMonoid Q] {k : T.LocalizationMap Q} (z : N),
  k (g ↑(f.sec z).2) * (f.map hy k) z = k (g (f.sec z).1)

Given Localization maps f : M →* N, k : P →* Q for Submonoids S, T respectively, if a CommMonoid homomorphism g : M →* P induces a f.map hy k : N →* Q, then for all z : N, we have k (g y) * f.map hy k z = k (g x) where x : M, y ∈ S are such that z * f y = f x.
