Nuprl Lemma : sq_stable__single-valued-iterated-classrel
∀[Info,A,S:Type].
∀init:Id ⟶ bag(S). ∀f:A ⟶ S ⟶ S. ∀X:EClass(A). ∀es:EO+(Info). ∀e:E. ∀v:S.
(single-valued-classrel(es;X;A)
⇒ single-valued-bag(init loc(e);S)
⇒ SqStable(iterated-classrel(es;S;A;f;init;X;e;v)))
Proof
Definitions occuring in Statement :
iterated-classrel: iterated-classrel(es;S;A;f;init;X;e;v),
single-valued-classrel: single-valued-classrel(es;X;T),
eclass: EClass(A[eo; e]),
event-ordering+: EO+(Info),
es-loc: loc(e),
es-E: E,
Id: Id,
sq_stable: SqStable(P),
uall: ∀[x:A]. B[x],
all: ∀x:A. B[x],
implies: P ⇒ Q,
apply: f a,
