Nuprl Lemma : ppcc-problem2
∀[es:EO]. ∀[e:E]. (False) supposing ((↑¬bfirst(e)) and (↑first(e)))
Proof
Definitions occuring in Statement :
es-first: first(e),
es-E: E,
event_ordering: EO,
bnot: ¬bb,
assert: ↑b,
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
false: False
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
uimplies: b supposing a,
false: False,
bnot: ¬bb,
ifthenelse: if b then t else f fi ,
btrue: tt,
and: P ∧ Q,
prop: ℙ,
not: ¬A,
implies: P ⇒ Q
Latex:
\mforall{}[es:EO]. \mforall{}[e:E]. (False) supposing ((\muparrow{}\mneg{}\msubb{}first(e)) and (\muparrow{}first(e)))
