Description: The orthocomplement of an indexed union. (Contributed by Mario Carneiro, 23-Oct-2015.)

Hypotheses

Ref	Expression
inocv.o	⊢ ⊥ = (ocv‘𝑊)
iunocv.v	⊢ 𝑉 = (Base‘𝑊)

Assertion

Ref	Expression
iunocv	⊢ ( ⊥ ‘∪ 𝑥 ∈ 𝐴 𝐵) = (𝑉 ∩ ∩ 𝑥 ∈ 𝐴 ( ⊥ ‘𝐵))

Distinct variable groups:   𝑥,𝑉   𝑥,𝑊

Allowed substitution hints:   𝐴(𝑥)   𝐵(𝑥)   ⊥ (𝑥)

Proof of Theorem iunocv

Dummy variables 𝑦 𝑧 are mutually distinct and distinct from all other variables.
