Nuprl Lemma : skip-first-class-is-empty-if-first

[Info,A:Type]. ∀[es:EO+(Info)]. ∀[e:E]. ∀[X:EClass(A)].  Skip(X) es {} supposing ↑first(e)


Proof




Definitions occuring in Statement :  skip-first-class: Skip(X) eclass: EClass(A[eo; e]) event-ordering+: EO+(Info) es-first: first(e) es-E: E assert: b uimplies: supposing a uall: [x:A]. B[x] apply: a universe: Type sqequal: t empty-bag: {}
