SUMMARY:Shin-Young Kim\, Minimal Rational Curves on Complete Symmetric Varieties
DESCRIPTION:    Speaker\n\n\nShin-Young Kim\nIBS-CGP\n\n\n\n\n\n\nWe describe the families of minimal rational curves on any complete symmetric variety\, and the corresponding varieties of minimal rational tangents. In particular\, we prove that these varieties are homogeneous and that for non-exceptional irreducible wonderful varieties\, there is a unique family of minimal rational curves. We relate these results to the restricted root system of the associated symmetric space. In particular\, for certain Fano wonderful symmetric varieties\, the VMRT has two connected components. This is a joint work with M.Brion and N. Perrin.
