Nuprl Lemma : sq_stable__geo-gt-prim
∀g:EuclideanPlaneStructure. ∀a,b,c,d:Point. SqStable(ab>cd)
Proof
Definitions occuring in Statement :
euclidean-plane-structure: EuclideanPlaneStructure,
geo-gt-prim: ab>cd,
geo-point: Point,
sq_stable: SqStable(P),
all: ∀x:A. B[x]
Definitions unfolded in proof :
subtype_rel: A ⊆r B,
prop: ℙ,
uall: ∀[x:A]. B[x],
btrue: tt,
ifthenelse: if b then t else f fi ,
eq_atom: x =a y,
record+: record+,
euclidean-plane-structure: EuclideanPlaneStructure,
record-select: r.x,
member: t ∈ T,
all: ∀x:A. B[x]
Latex:
