Nuprl Lemma : uanti_sym_wf
∀[T:Type]. ∀[R:T ⟶ T ⟶ ℙ]. (UniformlyAntiSym(T;x,y.R[x;y]) ∈ ℙ)
Proof
Definitions occuring in Statement :
uanti_sym: UniformlyAntiSym(T;x,y.R[x; y]),
uall: ∀[x:A]. B[x],
prop: ℙ,
so_apply: x[s1;s2],
member: t ∈ T,
function: x:A ⟶ B[x],
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
uanti_sym: UniformlyAntiSym(T;x,y.R[x; y]),
so_lambda: λ2x.t[x],
uimplies: b supposing a,
so_apply: x[s1;s2],
subtype_rel: A ⊆r B,
so_apply: x[s],
prop: ℙ
