%0 Journal Article %T Killing Fields of Holomorphic Cartan Geometries %A Sorin Dumitrescu %J Mathematics %D 2009 %I arXiv %X We study local automorphisms of holomorphic Cartan geometries. This leads to classification results for compact complex manifolds admitting Cartan geometries. We prove that a compact Calabi-Yau manifold bearing a holomorphic Cartan geometry of algebraic type admits a finite unramified cover which is a complex torus. %U http://arxiv.org/abs/0902.2193v2
