Nuprl Lemma : per-quotient_wf

[T:Type]. ∀[E:T ⟶ T ⟶ ℙ].  x,y:T/per/E[x;y] ∈ Type supposing EquivRel(T;x,y.E[x;y])


Proof




Definitions occuring in Statement :  per-quotient: x,y:T/per/E[x; y] equiv_rel: EquivRel(T;x,y.E[x; y]) uimplies: supposing a uall: [x:A]. B[x] prop: so_apply: x[s1;s2] member: t ∈ T function: x:A ⟶ B[x] universe: Type
Definitions unfolded in proof :  per-quotient: x,y:T/per/E[x; y] quotient: x,y:A//B[x; y]
