Abstract:
Rigidity of projective homogeneous varieties and Lie algebra cohomology.
Abstract: The problem of identifying homogeneous varieties from their local differential geometry dates back to Monge, and has been studied by Fubini, Griffiths and Harris, Hwang and Yamaguchi, and others. I will describe recent work with J.M. Landsberg that establishes a general recognition theorem. The key component is the resolution of exterior differential systems by Lie algebra cohomology.
