Nuprl Lemma : es-interface-predecessors-equal

[Info:Type]. ∀[es:EO+(Info)]. ∀[X,Y:EClass(Top)].
  ∀[e:E]. (≤(X)(e) = ≤(Y)(e) ∈ (E(X) List)) supposing ∀e:E. (↑e ∈b ⇐⇒ ↑e ∈b Y)


Proof




Definitions occuring in Statement :  es-interface-predecessors: (X)(e) es-E-interface: E(X) in-eclass: e ∈b X eclass: EClass(A[eo; e]) event-ordering+: EO+(Info) es-E: E list: List assert: b uimplies: supposing a uall: [x:A]. B[x] top: Top all: x:A. B[x] iff: ⇐⇒ Q universe: Type equal: t ∈ T
