Nuprl Lemma : decidable__exists_classrel
∀[Info,T:Type]. ∀X:EClass(T). ∀es:EO+(Info). ∀e:E. Dec(↓∃v:T. v ∈ X(e))
Proof
Definitions occuring in Statement :
classrel: v ∈ X(e),
eclass: EClass(A[eo; e]),
event-ordering+: EO+(Info),
es-E: E,
decidable: Dec(P),
uall: ∀[x:A]. B[x],
all: ∀x:A. B[x],
exists: ∃x:A. B[x],
squash: ↓T,
universe: Type
