Abstract

In this paper, we give a non-existence theorem of Hopf hypersurfaces in complex two-plane Grassmannians $\GBt$, $m \geq 3$, whose shape operator is of Codazzi type in generalized Tanaka-Webster connection $\gtw$.

Keywords: complex two-plane Grassmannians, Hopf hypersurface, generalized Tanaka-Webster connection, shape operator, Codazzi type tensor
