Ref Expression
rnghmval ((𝑅 ∈ Rng ∧ 𝑆 ∈ Rng) → (𝑅 RngHomo 𝑆) = {𝑓 ∈ (𝐶m 𝐵) ∣ ∀𝑥𝐵𝑦𝐵 ((𝑓‘(𝑥 + 𝑦)) = ((𝑓𝑥) (𝑓𝑦)) ∧ (𝑓‘(𝑥 · 𝑦)) = ((𝑓𝑥) (𝑓𝑦)))})
Distinct variable groups:   𝐵,𝑓,𝑥,𝑦   𝑅,𝑓,𝑥,𝑦   𝑆,𝑓,𝑥,𝑦   𝐶,𝑓
Allowed substitution hints:   𝐶(𝑥,𝑦)   + (𝑥,𝑦,𝑓)   (𝑥,𝑦,𝑓)   · (𝑥,𝑦,𝑓)   (𝑥,𝑦,𝑓)

Proof of Theorem rnghmval
Dummy variables 𝑟 𝑠 𝑣 𝑤 are mutually distinct and distinct from all other variables.
