Nuprl Lemma : mFOL-proveable-formula_wf
∀[fmla:mFOL()]. (mFOL-proveable-formula(fmla) ∈ ℙ)
Proof
Definitions occuring in Statement :
mFOL-proveable-formula: mFOL-proveable-formula(fmla),
mFOL: mFOL(),
uall: ∀[x:A]. B[x],
prop: ℙ,
member: t ∈ T
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
mFOL-proveable-formula: mFOL-proveable-formula(fmla),
subtype_rel: A ⊆r B,
mFOL-sequent: mFOL-sequent(),
so_lambda: λ2x.t[x],
so_apply: x[s],
uimplies: b supposing a,
all: ∀x:A. B[x]
