Nuprl Lemma : State-comb-classrel2
∀[Info,B,A:Type]. ∀[f:A ⟶ B ⟶ B]. ∀[init:Id ⟶ bag(B)].
∀X:EClass(A). ∀es:EO+(Info). ∀e:E. ∀[v:B]. (v ∈ State-comb(init;f;X)(e) ⇐⇒ ↓iterated-classrel(es;B;A;f;init;X;e;v))
Proof
Definitions occuring in Statement :
State-comb: State-comb(init;f;X),
iterated-classrel: iterated-classrel(es;S;A;f;init;X;e;v),
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],
iff: P ⇐⇒ Q,
squash: ↓T,
function: x:A ⟶ B[x],
