Theorem ovigg 5597

Description: The value of an operation class abstraction. Compare ovig 5598. The condition (x ∈ R ∧ y ∈ S) is been removed. (Contributed by FL, 24-Mar-2007.)

Hypotheses

Ref	Expression
ovigg.1	⊢ ((x = A ∧ y = B ∧ z = C) → (φ ↔ ψ))
ovigg.4	⊢ ∃*zφ
ovigg.5	⊢ F = {⟨⟨x, y⟩, z⟩ ∣ φ}

Assertion

Ref	Expression
ovigg	⊢ ((A ∈ V ∧ B ∈ W ∧ C ∈ X) → (ψ → (AFB) = C))

Distinct variable groups:   x,y,z,A   x,B,y,z   x,C,y,z   ψ,x,y,z

Allowed substitution hints:   φ(x,y,z)   F(x,y,z)   V(x,y,z)   W(x,y,z)   X(x,y,z)
