Nuprl Lemma : member-es-le-before2

es:EO. ∀e:E. ∀e':{a:E| loc(a) loc(e) ∈ Id} .  ((e' ∈ ≤loc(e)) ⇐⇒ e' ≤loc )


Proof




Definitions occuring in Statement :  es-le-before: loc(e) es-le: e ≤loc e'  es-loc: loc(e) es-E: E event_ordering: EO Id: Id l_member: (x ∈ l) all: x:A. B[x] iff: ⇐⇒ Q set: {x:A| B[x]}  equal: t ∈ T
Definitions unfolded in proof :  all: x:A. B[x] member: t ∈ T iff: ⇐⇒ Q and: P ∧ Q implies:  Q l_member: (x ∈ l) exists: x:A. B[x] cand: c∧ B subtype_rel: A ⊆B uall: [x:A]. B[x] prop: nat: uimplies: supposing a ge: i ≥  decidable: Dec(P) or: P ∨ Q satisfiable_int_formula: satisfiable_int_formula(fmla) false: False not: ¬A top: Top rev_implies:  Q
