Nuprl Lemma : null_mset_wf
∀s:DSet. (0{s} ∈ MSet{s})
Proof
Definitions occuring in Statement :
null_mset: 0{s},
mset: MSet{s},
all: ∀x:A. B[x],
member: t ∈ T,
dset: DSet
Definitions unfolded in proof :
null_mset: 0{s},
all: ∀x:A. B[x],
member: t ∈ T,
mset: MSet{s},
uall: ∀[x:A]. B[x],
dset: DSet,
so_lambda: λ2x y.t[x; y],
so_apply: x[s1;s2],
uimplies: b supposing a,
implies: P ⇒ Q
