Nuprl Lemma : eo-restrict_wf

[es:EO]. ∀[P:E ⟶ 𝔹].  (eo-restrict(es;P) ∈ EO)


Proof




Definitions occuring in Statement :  eo-restrict: eo-restrict(eo;P) es-E: E event_ordering: EO bool: 𝔹 uall: [x:A]. B[x] member: t ∈ T function: x:A ⟶ B[x]
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T eo-restrict: eo-restrict(eo;P) eo-reset-dom: eo-reset-dom(es;d) es-dom: es-dom(es) es-E: E es-base-E: es-base-E(es) all: x:A. B[x] implies:  Q bool: 𝔹 unit: Unit it: btrue: tt band: p ∧b q ifthenelse: if then else fi  uiff: uiff(P;Q) and: P ∧ Q uimplies: supposing a prop: bfalse: ff
