Morphisms of polar spacesClaudeAlain Faure and Gavin J. SealGymnase de la Cit{é}, CP 329, 1000 Lausanne 17, VD, Switzerland, email: cafaure@bluemail.ch; G. J. Seal c/o G. Cedraschi, 1 R. des Minoteries, 1205 Geneva, Switzerland, email: gseal@fastmail.fmAbstract: Polar spaces are presented from the point of view of paraprojective spaces. Morphisms are introduced and some immediate categorical aspects are reviewed. The morphisms of polar spaces are then studied in more details and are shown to preserve the spaces' structure. Finally, it is shown that a morphism of polar spaces can be split into a morphism of nondegenerate polar spaces and a morphism of projective spaces. Full text of the article:
