Theorem islmhm3 19028

Description: Property of a module homomorphism, similar to ismhm 17337. (Contributed by Stefan O'Rear, 7-Mar-2015.)

Hypotheses

Ref	Expression
islmhm.k	⊢ 𝐾 = (Scalar‘𝑆)
islmhm.l	⊢ 𝐿 = (Scalar‘𝑇)
islmhm.b	⊢ 𝐵 = (Base‘𝐾)
islmhm.e	⊢ 𝐸 = (Base‘𝑆)
islmhm.m	⊢ · = ( ·𝑠 ‘𝑆)
islmhm.n	⊢ × = ( ·𝑠 ‘𝑇)

Assertion

Ref	Expression
islmhm3	⊢ ((𝑆 ∈ LMod ∧ 𝑇 ∈ LMod) → (𝐹 ∈ (𝑆 LMHom 𝑇) ↔ (𝐹 ∈ (𝑆 GrpHom 𝑇) ∧ 𝐿 = 𝐾 ∧ ∀𝑥 ∈ 𝐵 ∀𝑦 ∈ 𝐸 (𝐹‘(𝑥 · 𝑦)) = (𝑥 × (𝐹‘𝑦)))))

Distinct variable groups:   𝑥,𝐵   𝑦,𝐸   𝑥,𝑦,𝑆   𝑥,𝐹,𝑦   𝑥,𝑇,𝑦

Allowed substitution hints:   𝐵(𝑦)   · (𝑥,𝑦)   × (𝑥,𝑦)   𝐸(𝑥)   𝐾(𝑥,𝑦)   𝐿(𝑥,𝑦)
