Theorem | cvmliftlem1 31814* | Lemma for cvmlift 31828. In cvmliftlem15 31827, we picked an 𝑁 large enough so that the sections (𝐺 “ [(𝑘 − 1) / 𝑁, 𝑘 / 𝑁]) are all contained in an even covering, and the function 𝑇 enumerates these even coverings.

Theorem | cvmliftlem6 31819* | Lemma for cvmlift 31828. Induction step for cvmliftlem7 31820. Assuming that 𝑄(𝑀 − 1) is defined at (𝑀 − 1) / 𝑁 and is a preimage of 𝐺((𝑀 − 1) / 𝑁), the next segment 𝑄(𝑀) is also defined and is a function on 𝑊 which is a lift 𝐺 for this segment.

Theorem | cvmliftlem10 31823* | Lemma for cvmlift 31828. The function 𝐾 is going to be our complete lifted path, formed by unioning together all the 𝑄 functions (each of which is defined on one segment [(𝑀 − 1) / 𝑁, 𝑀 / 𝑁] of the interval). Here we prove by induction that 𝐾 is a continuous function and a lift of 𝐺 by applying cvmliftlem6 31819, cvmliftlem7 31820 (to show it is a function and a lift), cvmliftlem8 31821 (to show it is continuous), and cvmliftlem9 31822 (to show that different 𝑄 functions agree on the intersection of their domains, so that the pasting lemma paste 21470 gives that 𝐾 is well-defined and continuous).

Theorem | cvmliftlem15 31827* | Lemma for cvmlift 31828. Discharge the assumptions of cvmliftlem14 31826. The set of all open subsets 𝑢 of the unit interval such that 𝐺 “ 𝑢 is contained in an even covering of some open set in 𝐽 is a cover of II by the definition of a covering map, so by the Lebesgue number lemma lebnumii 23136, there is a subdivision of the closed unit interval into 𝑁 equal parts such that each part is entirely contained within one such open set of 𝐽. Then using finite choice ac6sfi 8474 to uniformly select one such subset and one even covering of each subset, we are ready to finish the proof with cvmliftlem14 31826.

Definition | df-sat 31872* |
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-goeq 31887* | Define the Godel-set of equality. Here the arguments 𝑥 = 〈𝑁, 𝑃〉 correspond to vN and vP , so (∅=𝑔1o) actually means v0 = v1 , not 0 = 1. Here we use the trick mentioned in ax-ext 2804 to introduce equality as a defined notion in terms of ∈𝑔. The expression suc (𝑢 ∪ 𝑣) = max (𝑢, 𝑣) + 1 here is a convenient way of getting a dummy variable distinct from 𝑢 and 𝑣. (Contributed by Mario Carneiro, 14-Jul-2013.) |

Definition | df-goex 31888 | Define the Godel-set of existential quantification. Here 𝑁 ∈ ω corresponds to vN , and 𝑈 represents another formula, and this expression is [∃𝑥𝜑] = ∃𝑔𝑁𝑈 where 𝑥 is the 𝑁-th variable, 𝑈 = [𝜑] is the code for 𝜑. Note that this is a class expression, not a wff. (Contributed by Mario Carneiro, 14-Jul-2013.) |

Definition | df-prv 31889* | Define the "proves" relation on a set. A wff is true in a model 𝑀 if for every valuation 𝑠 ∈ (𝑀 ↑𝑚 ω), the interpretation of the wff using the membership relation on 𝑀 is true. (Contributed by Mario Carneiro, 14-Jul-2013.) |
