SUMMARY:Sung-Yeon Kim\, Real orbits in flag manifolds
DESCRIPTION:    Speaker\n\n\nSung-Yeon Kim\nIBS CCG\n\n\n\n\n\n\nLet G​ be a complex semisimple Lie group\, P​​ be a parabolic subgroup and G0​​ be a real form of G.​​ Then the flag manifold G/P​​ decomposes into finitely many G0-orbits. The complex structure of G/P​​ yields a natural homogeneous CR manifold structure on the real orbits such that all elements in G0 are CR automorphisms. Among them there is exactly one orbit of minimal dimension\, which is compact. Shilov boundary of bounded symmetric domains are the well-known examples of such minimal orbits. In this talk\, we study real orbits from the point of view of CR geometry. In particular we study the CR structures on the minimal orbits in Grassmannians.
