Nuprl Lemma : subtype_rel_list

[A,B:Type].  (A List) ⊆(B List) supposing A ⊆B


Proof




Definitions occuring in Statement :  list: List uimplies: supposing a subtype_rel: A ⊆B uall: [x:A]. B[x] universe: Type
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T uimplies: supposing a list: List so_lambda: λ2x.t[x] nat: so_apply: x[s] all: x:A. B[x] implies:  Q prop: subtype_rel: A ⊆B
