Title: Parallelism of shape operator on real hypersurfaces in complex two-plane Grassmannians
Speaker: Dr. Hyeonjin Lee (POSTECH)
Abstract:
In this talk, we want to introduce a notion of the Reeb parallel shape operator with respect to the Levi-Civita connection (or the generalized Tanaka-Webster connec- tion [1], resp.) of a real hypersurface in G2(Cm+2) and give some characterizations for model spaces related to the parallelism of shape operator (see [2], [3], and so on).
