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…

Some open problems and conjectures on submanifolds of finite type: recent development
Submanifolds of finite type were introduced by the author during the late 1970s. The first results on this subject were collected in author's books [26,29]. In 1991, a list of twelve open problems…

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…

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…
