Theorem prv 33290
Description: The "proves" relation on a set. A wff encoded as 𝑈 is true in a model 𝑀 iff for every valuation 𝑠 ∈ (𝑀m ω), the interpretation of the wff using the membership relation on 𝑀 is true. (Contributed by AV, 5-Nov-2023.)
Assertion
Ref Expression
prv ((𝑀𝑉𝑈𝑊) → (𝑀𝑈 ↔ (𝑀 Sat 𝑈) = (𝑀m ω)))

Proof of Theorem prv
Dummy variables 𝑚 𝑢 are mutually distinct and distinct from all other variables.
