Nuprl Lemma : ts-stable-rel_wf

[ts:transition-system{i:l}]. ∀[R:ts-type(ts) ⟶ ts-type(ts) ⟶ ℙ].  (ts-stable-rel(ts;x,y.R[x;y]) ∈ ℙ)


Proof




Definitions occuring in Statement :  ts-stable-rel: ts-stable-rel(ts;x,y.R[x; y]) ts-type: ts-type(ts) transition-system: transition-system{i:l} uall: [x:A]. B[x] prop: so_apply: x[s1;s2] member: t ∈ T function: x:A ⟶ B[x]
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T ts-stable-rel: ts-stable-rel(ts;x,y.R[x; y]) so_lambda: λ2x.t[x] implies:  Q prop: infix_ap: y so_apply: x[s1;s2] so_apply: x[s]
