Nuprl Lemma : bind-zero-left

[Info,T,S:Type].  ∀f:T ─→ EClass(S). (Empty >z> f[z] Empty ∈ EClass(S))


Proof




Definitions occuring in Statement :  bind-class: X >x> Y[x] es-empty-interface: Empty eclass: EClass(A[eo; e]) uall: [x:A]. B[x] so_apply: x[s] all: x:A. B[x] function: x:A ─→ B[x] universe: Type equal: t ∈ T
