Journal of Lie Theory 23 (2013), No. 4, 1129--1160 Copyright Heldermann Verlag 2013 Castling Transformations of Projective Structures Hironao Kato Advanced Mathematical Institute, Osaka City University, 3-3-138 Sugimoto, Sumiyoshi-ku, Osaka 558-8585, Japan and: Dept. of Mathematics, King's College, Strand, London WC2R 2LS, England katohiro@sci.osaka-cu.ac.jp We construct an infinite sequence of projectively flat manifolds by using castling transformations of prehomogeneous vector spaces. We also give a classification of manifolds equipped with a flat projective structure obtained by a finite number of castling transformations, and describe these flat projective structures by atlases. Keywords: Projective structure, Grassmannian structure, prehomogeneous vector space. MSC: 53B10, 11S90; 53C10 [ Fulltext-pdf (456 KB)] for subscribers only. |
