Nuprl Lemma : State-classrel

[Info,B,A:Type]. ∀[f:A ⟶ B ⟶ B]. ∀[init:Id ⟶ bag(B)].
  ∀X:EClass(A). ∀es:EO+(Info). ∀e:E.  ∀[v:B]. (v ∈ State-class(init;f;X)(e) ⇐⇒ iterated_classrel(es;B;A;f;init;X;e;v))


Proof




Definitions occuring in Statement :  State-class: State-class(init;f;X) iterated_classrel: iterated_classrel(es;S;A;f;init;X;e;v) classrel: v ∈ X(e) eclass: EClass(A[eo; e]) event-ordering+: EO+(Info) es-E: E Id: Id uall: [x:A]. B[x] all: x:A. B[x] iff: ⇐⇒ Q function: x:A ⟶ B[x] universe: Type bag: bag(T)
Definitions unfolded in proof :  uall: [x:A]. B[x] all: x:A. B[x] iff: ⇐⇒ Q and: P ∧ Q implies:  Q squash: T member: t ∈ T prop: rev_implies:  Q classrel: v ∈ X(e) bag-member: x ↓∈ bs so_lambda: λ2x.t[x] so_apply: x[s] subtype_rel: A ⊆B uiff: uiff(P;Q) uimplies: supposing a exists: x:A. B[x] or: P ∨ Q so_lambda: λ2y.t[x; y] so_apply: x[s1;s2] State-class: State-class(init;f;X) simple-comb-2: F|X, Y| simple-comb: simple-comb(F;Xs) select: L[n] cons: [a b] subtract: m eclass: EClass(A[eo; e]) sq_type: SQType(T) guard: {T} ifthenelse: if then else fi  btrue: tt not: ¬A bfalse: ff cand: c∧ B false: False sq_stable: SqStable(P) bool: 𝔹 unit: Unit it: bnot: ¬bb assert: b rev_uimplies: rev_uimplies(P;Q)
