∀[X:⊢''']. ∀[lvl:ℕ4]. ∀[T:{X ⊢lvl _}]. (var-term-meaning(lvl;T) ∈ cttTerm(X.T))
Proof
Definitions occuring in Statement :
var-term-meaning: var-term-meaning(lvl;T),
ctt-term-meaning: cttTerm(X),
ctt-level-type: {X ⊢lvl _},
cube-context-adjoin: X.A,
cubical_set: CubicalSet,
int_seg: {i..j-},
uall: ∀[x:A]. B[x],
member: t ∈ T,
natural_number: $n
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
subtype_rel: A ⊆r B,
var-term-meaning: var-term-meaning(lvl;T),
nat: ℕ,
int_seg: {i..j-},
lelt: i ≤ j < k,
and: P ∧ Q,
le: A ≤ B,
less_than: a < b,
squash: ↓T,
all: ∀x:A. B[x],
decidable: Dec(P),
or: P ∨ Q,
uimplies: b supposing a,
not: ¬A,
implies: P ⇒ Q,
satisfiable_int_formula: satisfiable_int_formula(fmla),
exists: ∃x:A. B[x],
false: False,
