Nuprl Lemma : projective-plane-structure_subtype
ProjectivePlaneStructure ⊆r ProjGeomPrimitives
Proof
Definitions occuring in Statement :
projective-plane-structure: ProjectivePlaneStructure,
pgeo-primitives: ProjGeomPrimitives,
subtype_rel: A ⊆r B
Definitions unfolded in proof :
subtype_rel: A ⊆r B,
member: t ∈ T,
projective-plane-structure: ProjectivePlaneStructure,
record+: record+,
record-select: r.x,
eq_atom: x =a y,
ifthenelse: if b then t else f fi ,
btrue: tt,
uall: ∀[x:A]. B[x],
all: ∀x:A. B[x],
prop: ℙ,
or: P ∨ Q,
implies: P ⇒ Q,
exists: ∃x:A. B[x],
and: P ∧ Q
