Assertion

Ref	Expression
rngcvalALTV	⊢ (𝜑 → 𝐶 = {⟨(Base‘ndx), 𝐵⟩, ⟨(Hom ‘ndx), 𝐻⟩, ⟨(comp‘ndx), · ⟩})

Distinct variable groups:   𝑓,𝑔,𝑣,𝑥,𝑦,𝑧   𝑣,𝐵,𝑥,𝑦,𝑧   𝑣,𝑈,𝑥,𝑦,𝑧   𝜑,𝑣,𝑥,𝑦,𝑧

Allowed substitution hints:   𝜑(𝑓, 𝑔)   𝐵(𝑓, 𝑔)   𝐶(𝑥, 𝑦, 𝑧, 𝑣, 𝑓, 𝑔)   · (𝑥, 𝑦, 𝑧, 𝑣, 𝑓, 𝑔)   𝑈(𝑓, 𝑔)   𝐻(𝑥, 𝑦, 𝑧, 𝑣, 𝑓, 𝑔)   𝑉(𝑥, 𝑦, 𝑧, 𝑣, 𝑓, 𝑔)

Proof of Theorem rngcvalALTV

Dummy variables 𝑏 𝑢 are mutually distinct and distinct from all other variables.
