Nuprl Lemma : mFOL-boundvars_wf
∀[fmla:mFOL()]. (mFOL-boundvars(fmla) ∈ ℤ List)
Proof
Definitions occuring in Statement :
mFOL-boundvars: mFOL-boundvars(fmla),
mFOL: mFOL(),
list: T List,
uall: ∀[x:A]. B[x],
member: t ∈ T,
int: ℤ
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
mFOL-boundvars: mFOL-boundvars(fmla),
so_lambda: λ2x y.t[x; y],
so_apply: x[s1;s2],
so_lambda: so_lambda(x,y,z,w,v.t[x; y; z; w; v]),
so_apply: x[s1;s2;s3;s4;s5],
so_lambda: so_lambda(x,y,z,w.t[x; y; z; w]),
so_apply: x[s1;s2;s3;s4]
