Nuprl Lemma : set-ss-point
∀[ss,P:Top]. (Point ~ {x:Point| P[x]} )
Proof
Definitions occuring in Statement :
set-ss: set-ss(ss;x.P[x]),
ss-point: Point,
uall: ∀[x:A]. B[x],
top: Top,
so_apply: x[s],
set: {x:A| B[x]} ,
sqequal: s ~ t
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
btrue: tt,
bfalse: ff,
ifthenelse: if b then t else f fi ,
eq_atom: x =a y,
top: Top,
member: t ∈ T,
all: ∀x:A. B[x],
mk-ss: mk-ss,
set-ss: set-ss(ss;x.P[x]),
ss-point: Point
