Nuprl Lemma : member-es-interval
∀es:EO. ∀e,e',ev:E. ((ev ∈ [e, e']) ⇐⇒ e ≤loc ev ∧ ev ≤loc e' )
Proof
Definitions occuring in Statement :
es-interval: [e, e'],
es-le: e ≤loc e' ,
es-E: E,
event_ordering: EO,
l_member: (x ∈ l),
all: ∀x:A. B[x],
iff: P ⇐⇒ Q,
and: P ∧ Q
Definitions unfolded in proof :
all: ∀x:A. B[x],
member: t ∈ T,
uall: ∀[x:A]. B[x],
es-interval: [e, e'],
iff: P ⇐⇒ Q,
and: P ∧ Q,
implies: P ⇒ Q,
prop: ℙ,
rev_implies: P ⇐ Q,
or: P ∨ Q,
false: False,
guard: {T},
es-le: e ≤loc e'
