Nuprl Lemma : DVp_Struct-struct_wf

[v:C_DVALUEp()]. DVp_Struct-struct(v) ∈ {a:Atom| (a ∈ DVp_Struct-lbls(v))}  ⟶ C_DVALUEp() supposing ↑DVp_Struct?(v)


Proof




Definitions occuring in Statement :  DVp_Struct-struct: DVp_Struct-struct(v) DVp_Struct-lbls: DVp_Struct-lbls(v) DVp_Struct?: DVp_Struct?(v) C_DVALUEp: C_DVALUEp() l_member: (x ∈ l) assert: b uimplies: supposing a uall: [x:A]. B[x] member: t ∈ T set: {x:A| B[x]}  function: x:A ⟶ B[x] atom: Atom
