Classification of locally projectively homogeneous torsion-less affine connections in the plane domainsOldrich Kowalski and Zdenek VlásekCharles University Prague, Faculty of Mathematics and Physics, Sokolovská 83, 186 75 Praha, Czech Republic, e-mail: kowalski@karlin.mff.cuni.cz \quad vlasek@karlin.mff.cuni.czAbstract: The aim of this paper is to classify (locally) all torsion-less locally projectively homogeneous affine connections on 2-dimensional manifolds. Especially, we express, in a simple and explicit form, all such connections which are not projectively flat (Theorem 1). We make also some conclusions from this classification (Theorem 2 and Theorem3). Keywords: two-dimensional manifolds with affine connection, projectively homogeneous connections, Lie algebras of vector fields, Killing vector fields Classification (MSC2000): 53B05, 53C30 Full text of the article:
