Description: Membership in the Caratheodory's construction. (Contributed by Glauco Siliprandi, 17-Aug-2020.)

Hypotheses

Ref	Expression
caragenel.o	⊢ (𝜑 → 𝑂 ∈ OutMeas)
caragenel.s	⊢ 𝑆 = (CaraGen‘𝑂)

Assertion

Ref	Expression
caragenel	⊢ (𝜑 → (𝐸 ∈ 𝑆 ↔ (𝐸 ∈ 𝒫 ∪ dom 𝑂 ∧ ∀𝑎 ∈ 𝒫 ∪ dom 𝑂((𝑂‘(𝑎 ∩ 𝐸)) +𝑒 (𝑂‘(𝑎 ∖ 𝐸))) = (𝑂‘𝑎))))

Distinct variable groups:   𝐸,𝑎   𝑂,𝑎

Allowed substitution hints:   𝜑(𝑎)   𝑆(𝑎)

Proof of Theorem caragenel

Dummy variable 𝑒 is distinct from all other variables.
