Nuprl Lemma : state-class1-exists

∀[Info,A,B:Type]. ∀[init:Id ─→ B]. ∀[f:Id ─→ A ─→ B ─→ B]. ∀[X:EClass(A)].
  ∀es:EO+(Info). ∀e:E.  (↓∃v:B. v ∈ state-class1(init;f;X)(e))


Proof




Definitions occuring in Statement :  state-class1: state-class1(init;tr;X),  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],  exists: ∃x:A. B[x],  squash: ↓T,  function: x:A ─→ B[x],  universe: Type
