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: b supposing a,  uall: ∀[x:A]. B[x],  exists: ∃x:A. B[x],  squash: ↓T,  apply: f a,  function: x:A ─→ B[x],  natural_number: $n,  universe: Type,  bag-size: #(bs),  bag: bag(T)
