 Description: Property of a module homomorphism, similar to ismhm 17950. (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 · = ( ·𝑠𝑆)
islmhm.n × = ( ·𝑠𝑇)
Assertion
Ref Expression
islmhm3 ((𝑆 ∈ LMod ∧ 𝑇 ∈ LMod) → (𝐹 ∈ (𝑆 LMHom 𝑇) ↔ (𝐹 ∈ (𝑆 GrpHom 𝑇) ∧ 𝐿 = 𝐾 ∧ ∀𝑥𝐵𝑦𝐸 (𝐹‘(𝑥 · 𝑦)) = (𝑥 × (𝐹𝑦)))))
