TLDR
In this article, a complete classification of isoparametric hypersurfaces with constant principal curvatures has been obtained in the sphere, but the classification has not been obtained until now.
Abstract
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 classification problem of isoparametric hypersurfaces, which has been solved in euclidean space by T. Levi-Civita [6] and B. Segre [11] and in hyperbolic space by E. Cartan [1]; in the sphere, however, a complete classification has not been obtained until now (for essential results see [1], [2], [3], [8], [9], [10], and the literature cited there).

Real hypersurfaces with two principal curvatures in complex projective and hyperbolic planes

TL;DR: In this paper, the first examples of real hypersurfaces with two nonconstant principal curvatures in complex projective and hyperbolic planes were found and classified, and it was shown that each such hypersurface is foliated by equidistant Lagrangian flat surfaces with parallel mean curvature or by principal orbits of a cohomogeneity two polar action.

Characterizations of some real hypersurfaces in a complex space form in terms of lie derivative

TL;DR: In this article, a complex Kaehlerian manifold of constant holomorphic sectional curvature c is defined as a complex space form, which is denoted by $M_n(c)$.

Trajectories for Sasakian magnetic fields on real hypersurfaces of type (B) in a complex hyperbolic space

TL;DR: On a real hypersurface in a Kahler manifold, this paper considered a natural closed 2-form associated with the almost contact metric structure induced by the Kahler structure, and treated trajectories under magnetic fields which are constant multiples of this 2 -form.

On homogeneous real hypersurfaces in a complex projective space

TL;DR: In this paper, the authors considered the problem of determining homogeneous real hypersurfaces in a complex projective space Pn(C) of complex dimension n(^>2) which are orbits under analytic subgroups of the projective unitary group PU(n-\\-\\)>.

Real hypersurfaces and complex submanifolds in complex projective space

TL;DR: In this paper, it was shown that a complex submanifold with constant principal curvatures is an open subset of a homogeneous hypersurface if and only if it has constant curvatures and Jt is principal.
