We classify Hopf hypersurfaces of non-flat complex space forms CPm(4) and CHm(−4), denoted jointly by CQm(4c), that are of 2-type in the sense of B. Y. Chen, via the embedding into a suitable (pseudo) Euclidean space of Hermitian matrices by projection operators. This complements and extends earlier classifications by Martinez-Ros (minimal case) and Udagawa (CMC case), who studied only hypersurfaces of CPm and assumed them to have constant mean curvature instead of being Hopf. Moreover, we…

{$1$}-type submanifolds of non-Euclidean complex space forms
The purpose of this paper is to prove a classification result for submanifolds of complex space forms which are immersed into a suitable Euclidean spaces of complex matrices in such way that the
Real hypersurfaces and complex submanifolds in complex projective space
Let M be a real hypersurface in /"'(C), J be the complex structure and | denote a unit normal vector field on M. We show that M is (an open subset of) a homogeneous hypersurface if and only if M has

In a recent work [8] J. Simons has established a formula for the Laplacian of the second fundamental form of a submanifold in a Riemannian manifold and has obtained an important application in the
Focal sets and real hypersurfaces in complex projective space

Let M be a real submanifold of CPm, and let J denote the complex structure. We begin by finding a formula for the location of the focal points of M in terms of its second fundamental form. This takes
Real hypersurfaces with constant principal curvatures in complex hyperbolic space.
Since E. Cartan's work in the late 30's the classification problem of hypersurfaces with constant principal curvatures is known to be far from trivial. In real space forms it leads to the well-known

Let M be a real hypersurface of a Kahler manifold $$(\overline M, J)$$ and let $$\xi$$ be its unit normal vector field. Then M is a CR submanifold of maximal CR dimension and $$\xi$$ is the
On some real hypersurfaces of a complex projective space
A principal circle bundle over a real hypersurface of a complex projective space CPn can be regarded as a hypersurface of an odddimensional sphere. From this standpoint we can establish a method to

In the last years, the use of an idea of A. Ros, [11], has meant an interesting progress in the study of several families of submanifoids of the complex projective space CPn. This idea essentially

By employing the standard isometric imbedding of CPn into the Euclidean space, a classification theorem for full, minimal, 2-type surfaces in CPn that are not ? holomorphic is given. All such compact
