Nuprl Lemma : Memory-loc-class-exists

[Info,B,A:Type]. ∀[f:Id ─→ A ─→ B ─→ B]. ∀[init:Id ─→ bag(B)]. ∀[X:EClass(A)]. ∀[es:EO+(Info)]. ∀[e:E].
  ↓∃v:B. v ∈ Memory-loc-class(f;init;X)(e) supposing 0 < #(init loc(e))


Proof




Definitions occuring in Statement :  Memory-loc-class: Memory-loc-class(f;init;X) classrel: v ∈ X(e) eclass: EClass(A[eo; e]) event-ordering+: EO+(Info) es-loc: loc(e) es-E: E Id: Id less_than: a < b uimplies: supposing a uall: [x:A]. B[x] exists: x:A. B[x] squash: T apply: a function: x:A ─→ B[x] natural_number: $n universe: Type bag-size: #(bs) bag: bag(T)
