Nuprl Lemma : es-pred-locl-implies-le

es:EO. ∀e1,e2:E.  ((¬↑first(e1))  (pred(e1) <loc e2)  e1 ≤loc e2 )


Proof




Definitions occuring in Statement :  es-le: e ≤loc e'  es-locl: (e <loc e') es-first: first(e) es-pred: pred(e) es-E: E event_ordering: EO assert: b all: x:A. B[x] not: ¬A implies:  Q
Definitions unfolded in proof :  all: x:A. B[x] implies:  Q member: t ∈ T iff: ⇐⇒ Q and: P ∧ Q rev_implies:  Q uall: [x:A]. B[x] uimplies: supposing a es-locl: (e <loc e') or: P ∨ Q guard: {T} prop: false: False
