Nuprl Lemma : causal-weak-predecessor_wf

[es:EO]. ∀[p:E ⟶ (E Top)].  (causal-weak-predecessor(es;p) ∈ ℙ)


Proof




Definitions occuring in Statement :  causal-weak-predecessor: causal-weak-predecessor(es;p) es-E: E event_ordering: EO uall: [x:A]. B[x] top: Top prop: member: t ∈ T function: x:A ⟶ B[x] union: left right
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T causal-weak-predecessor: causal-weak-predecessor(es;p) so_lambda: λ2x.t[x] implies:  Q prop: subtype_rel: A ⊆B so_apply: x[s] uimplies: supposing a all: x:A. B[x] top: Top

Latex:
\mforall{}[es:EO].  \mforall{}[p:E  {}\mrightarrow{}  (E  +  Top)].    (causal-weak-predecessor(es;p)  \mmember{}  \mBbbP{})
