Theorem | cvmliftlem6 30526* | Lemma for cvmlift 30535. Induction step for cvmliftlem7 30527.

Definition | df-sat 30579* |
Define the satisfaction predicate. This recursive construction builds up
a function over wff codes and simultaneously defines the set of
assignments to all variables from 𝑀 that makes the coded wff true in
the model 𝑀, where ∈ is interpreted as the binary relation 𝐸 on 𝑀.
The interpretation of the statement 𝑆 ∈ (((𝑀 Sat 𝐸)‘𝑛)‘𝑈) is that for the model 〈𝑀, 𝐸〉, 𝑆:ω⟶𝑀 is a
valuation of the variables (v0 = (𝑆‘∅), v1 = (𝑆‘1𝑜), etc.) and 𝑈 is a code for a wff using ∈ , ⊼ , ∀ that
is true under the assignment 𝑆. The function is defined by finite
recursion; ((𝑀 Sat 𝐸)‘𝑛) only operates on wffs of depth at
most 𝑛 ∈ ω, and ((𝑀 Sat 𝐸)‘ω) = ∪ 𝑛 ∈ ω((𝑀 Sat 𝐸)‘𝑛) operates on all wffs.
The coding scheme for the wffs is defined so that

Definition | df-fmla 30581 | Define the predicate which defines the set of valid Godel formulas. The parameter 𝑛 defines the maximum height of the formulas: the set (Fmla‘∅) is all formulas of the form 𝑥 = 𝑦 or 𝑥 ∈ 𝑦 (which in our coding scheme is the set ({∅, 1𝑜} × (ω × ω)); see df-sat 30579 for the full coding scheme), and each extra level adds to the complexity of the formulas in (Fmla‘𝑛). (Fmla‘ω) = ∪ 𝑛 ∈ ω(Fmla‘𝑛) is the set of all valid formulas. (Contributed by Mario Carneiro, 14-Jul-2013.) |
