∀[ss:SeparationSpace]. ∀[x,y:Point]. (x # y ∈ ℙ)
Proof
Definitions occuring in Statement :
ss-sep: x # y,
ss-point: Point,
separation-space: SeparationSpace,
uall: ∀[x:A]. B[x],
prop: ℙ,
member: t ∈ T
Definitions unfolded in proof :
ss-point: Point,
ss-sep: x # y,
or: P ∨ Q,
all: ∀x:A. B[x],
implies: P ⇒ Q,
so_apply: x[s],
so_lambda: λ2x.t[x],
prop: ℙ,
guard: {T},
btrue: tt,
ifthenelse: if b then t else f fi ,
eq_atom: x =a y,
subtype_rel: A ⊆r B,
record-select: r.x,
record+: record+,
separation-space: SeparationSpace,
member: t ∈ T,
