Nuprl Lemma : comb_for_mset_map_wf
λs,s',f,a,z. msmap{s,s'}(f;a) ∈ s:DSet ⟶ s':DSet ⟶ f:(|s| ⟶ |s'|) ⟶ a:MSet{s} ⟶ (↓True) ⟶ MSet{s'}
Proof
Definitions occuring in Statement :
mset_map: msmap{s,s'}(f;a),
mset: MSet{s},
squash: ↓T,
true: True,
member: t ∈ T,
lambda: λx.A[x],
function: x:A ⟶ B[x],
dset: DSet,
set_car: |p|
Definitions unfolded in proof :
member: t ∈ T,
squash: ↓T,
all: ∀x:A. B[x],
uall: ∀[x:A]. B[x],
prop: ℙ,
dset: DSet
