On Boundedness of Maximal Operators Associated with Hypersurfaces
In this paper, we obtain the criterion of boundedness of maximal operators associated with smooth hypersurfaces. Also we compute the exact value of the boundedness index of such operators associated with arbitrary convex analytic hypersurfaces in the ...

On Bernstein’s Problem of Complete Parabolic Hypersurfaces in Warped Products
We study constant mean curvature hypersurfaces constructed over the fiber Mn of warped products I×fMn. In this setting, assuming that the sign of the angle function does not changed along the hypersurfaces, we infer the uniqueness of such hypersurfaces ...

Nonrational hypersurfaces [PDF]
In this very interesting paper there are developed some general ideas to obtain examples of Fano varieties, non-rational and not even ruled. -- Complete proofs, here only sketched, will appear elsewhere. The results are valid for ``very general'' hypersurfaces, that is they hold for hypersurfaces corresponding to a point in the complement of countably ...

Irreducibility of Hypersurfaces [PDF]
Given a polynomial P in several variables over an algebraically closed field, we show that except in some special cases that we fully describe, if one coefficient is allowed to vary, then the polynomial is irreducible for all but at most deg(P)^2-1 values of the coefficient.

On Einstein null hypersurfaces of $(LCS)_{n+2}$-space forms [PDF]
We show that ascreen null hypersurfaces of an (n+2)-dimensional Lorentzian concircular structure (LCS)_{n+2}-manifold admits an induced Ricci tensor. We, therefore, prove, under some geometric conditions, that an Einstein ascreen null hypersurface is ...

A characterization of totally $\eta$-umbilical real hypersurfaces and ruled real hypersurfaces of a complex space form [PDF]
summary:We give a characterization of totally $\eta $-umbilical real hypersurfaces and ruled real hypersurfaces of a complex space form in terms of totally umbilical condition for the holomorphic distribution on real hypersurfaces.

We study lightlike hypersurfaces of a semi-Riemannian product manifold. We introduce a class of lightlike hypersurfaces called screen semi-invariant lightlike hypersurfaces and radical anti-invariant lightlike hypersurfaces.
