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: supposing a uall: [x:A]. B[x] false: False
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T uimplies: supposing a false: False bnot: ¬bb ifthenelse: if then else fi  btrue: tt and: P ∧ Q prop: not: ¬A implies:  Q

Latex:
\mforall{}[es:EO].  \mforall{}[e:E].    (False)  supposing  ((\muparrow{}\mneg{}\msubb{}first(e))  and  (\muparrow{}first(e)))
