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
Definitions unfolded in proof :
