Nuprl Lemma : sq_stable__fseg

[T:Type]. ∀l1,l2:T List.  SqStable(fseg(T;l1;l2))


Proof




Definitions occuring in Statement :  fseg: fseg(T;L1;L2) list: List sq_stable: SqStable(P) uall: [x:A]. B[x] all: x:A. B[x] universe: Type
Definitions unfolded in proof :  fseg: fseg(T;L1;L2) uall: [x:A]. B[x] all: x:A. B[x] sq_stable: SqStable(P) implies:  Q exists: x:A. B[x] member: t ∈ T squash: T prop: uimplies: supposing a top: Top decidable: Dec(P) or: P ∨ Q satisfiable_int_formula: satisfiable_int_formula(fmla) false: False not: ¬A sq_type: SQType(T) guard: {T} subtype_rel: A ⊆B int_seg: {i..j-} lelt: i ≤ j < k and: P ∧ Q ge: i ≥  le: A ≤ B true: True so_lambda: λ2x.t[x] so_apply: x[s]
