Hypotheses

Ref	Expression
ismhm0.b	⊢ 𝐵 = (Base‘𝑆)
ismhm0.c	⊢ 𝐶 = (Base‘𝑇)
ismhm0.p	⊢ + = (+g‘𝑆)
ismhm0.q	⊢ ⨣ = (+g‘𝑇)
ismhm0.z	⊢ 0 = (0g‘𝑆)
ismhm0.y	⊢ 𝑌 = (0g‘𝑇)

Assertion

Ref	Expression
ismhm0	⊢ (𝐹 ∈ (𝑆 MndHom 𝑇) ↔ ((𝑆 ∈ Mnd ∧ 𝑇 ∈ Mnd) ∧ (𝐹 ∈ (𝑆 MgmHom 𝑇) ∧ (𝐹‘ 0 ) = 𝑌)))

Proof of Theorem ismhm0

Dummy variables 𝑥 𝑦 are mutually distinct and distinct from all other variables.
