Nuprl Lemma : interleaving_wf

[T:Type]. ∀[L1,L2,L:T List].  (interleaving(T;L1;L2;L) ∈ ℙ)


Proof




Definitions occuring in Statement :  interleaving: interleaving(T;L1;L2;L) list: List uall: [x:A]. B[x] prop: member: t ∈ T universe: Type
Definitions unfolded in proof :  interleaving: interleaving(T;L1;L2;L) uall: [x:A]. B[x] member: t ∈ T prop: and: P ∧ Q nat: all: x:A. B[x] implies:  Q guard: {T} ge: i ≥  decidable: Dec(P) or: P ∨ Q false: False uiff: uiff(P;Q) uimplies: supposing a satisfiable_int_formula: satisfiable_int_formula(fmla) exists: x:A. B[x] not: ¬A top: Top
