Recurrent Jacobi Operator of Real Hypersurfaces in Complex Two-plane Grassmannians
In this paper we give a non-existence theorem for Hopf hypersurfaces in the complex two-plane Grassmannian G2(C) with recurrent normal Jacobi operator R̄N .
متن کاملHypersurfaces of a Sasakian space form with recurrent shape operator
Let $(M^{2n},g)$ be a real hypersurface with recurrent shapeoperator and tangent to the structure vector field $xi$ of the Sasakian space form$widetilde{M}(c)$. We show that if the shape operator $A$ of $M$ isrecurrent then it is parallel. Moreover, we show that $M$is locally a product of two constant $phi-$sectional curvaturespaces.
متن کاملReal Hypersurfaces with Constant Principal Curvatures in Complex Hyperbolic Spaces
We present the classification of all real hypersurfaces in complex hyperbolic space CHn, n ≥ 3, with three distinct constant principal curvatures.

متن کاملHomogeneous Hypersurfaces in Complex Hyperbolic Spaces
We study the geometry of homogeneous hypersurfaces and their focal sets in complex hyperbolic spaces. In particular, we provide a characterization of the focal set in terms of its second fundamental form and determine the principal curvatures of the homogeneous hypersurfaces together with their multiplicities.
