Categorical aspects in projective geometry

Faure, Claude-Alain
Published in Applied Categorical Structures. 1998, vol. 6, no. 1, p. 87 - 103
Abstract After introducing morphisms between projective geometries, some categorical questions are examined. It is shown that there are three kinds of embeddings and two kinds of quotients. Furthermore the morphisms decompose in a canonical way into four factors.
