Title: Study of real hypersurfaces in complex hyperbolic two-plane Grassmannians with Ricci tensors

Speaker: Changhwa Woo (Kyungpook National University)

Abstract: In this paper, we introduce a new commuting condition between the structure Jacobi operator and symmetric (1,1)-type tensor field $T$, that is, $R_\xi\phi T=TR_\xi \phi$, where $T=A$ or $T=S$ for Hopf hypersurfaces in complex hyperbolic two-plane Grassmannians. By using simultaneous diagonalzation for commuting symmetric operators, We give a complete classification of real hypersurfaces in complex hyperbolic two-plane Grassmannians with commuting condition respectively.
