Nuprl Lemma : sq_stable__pgeo-axioms

∀g:ProjectivePlaneStructure. SqStable(BasicProjectiveGeometryAxioms(g))


Proof




Definitions occuring in Statement :  projective-plane-structure: ProjectivePlaneStructure,  basic-pgeo-axioms: BasicProjectiveGeometryAxioms(g),  sq_stable: SqStable(P),  all: ∀x:A. B[x]
Definitions unfolded in proof :  all: ∀x:A. B[x],  uall: ∀[x:A]. B[x],  member: t ∈ T,  subtype_rel: A ⊆r B,  implies: P ⇒ Q
