Nuprl Lemma : es-fix-causle
∀[Info:Type]. ∀es:EO+(Info). ∀X:EClass(Top). ∀f:E(X) ⟶ E(X). ((∀x:E(X). f x c≤ x) ⇒ (∀e:E(X). f**(e) c≤ e))
Proof
Definitions occuring in Statement :
es-E-interface: E(X),
eclass: EClass(A[eo; e]),
event-ordering+: EO+(Info),
es-fix: f**(e),
es-causle: e c≤ e',
uall: ∀[x:A]. B[x],
top: Top,
all: ∀x:A. B[x],
implies: P ⇒ Q,
apply: f a,
function: x:A ⟶ B[x],
universe: Type
Definitions unfolded in proof :
