Nuprl Lemma : decidable__exists-classrel-between1
∀[Info,T:Type]. ∀X:EClass(T). ∀es:EO+(Info). ∀e1,e2:E. Dec(∃e:E. (e1 ≤loc e ∧ (e <loc e2) ∧ (↓∃v:T. v ∈ X(e))))
Proof
Definitions occuring in Statement :
classrel: v ∈ X(e),
eclass: EClass(A[eo; e]),
event-ordering+: EO+(Info),
es-le: e ≤loc e' ,
es-locl: (e <loc e'),
es-E: E,
decidable: Dec(P),
uall: ∀[x:A]. B[x],
all: ∀x:A. B[x],
exists: ∃x:A. B[x],
squash: ↓T,
and: P ∧ Q,
universe: Type
