Homogeneous real hypersurfaces [PDF]

open access: yesMathematical Research Letters, 1995
Let \(M\) be an analytic real hypersurface through the origin in \(\mathbb{C}^n\). The hypersurface \(M\) is called weighted homogeneous if it is locally equivalent, via a biholomorphic map which preserves the origin, to a hypersurface given by an equation of the form \(P(z, \overline z) = 0\), where \(P\) is a polynomial which is homogeneous with ...

The Viro Method for Construction of Piecewise Algebraic Hypersurfaces

open access: yesAbstract and Applied Analysis, 2013
We propose a new method to construct a real piecewise algebraic hypersurface of a given degree with a prescribed smoothness and topology. The method is based on the smooth blending theory and the Viro method for construction of Bernstein-Bézier algebraic

On Normal Forms for Levi-flat hypersurfaces with an Isolated Line Singularity [PDF]

open access: yes, 2014
We prove the existence of normal forms for some local real-analytic Levi-flat hypersurfaces with an isolated line singularity. We also give sufficient conditions for that a Levi-flat hypersurface with a complex line as singularity to be a pullback of a ...

Non-embeddable real algebraic hypersurfaces [PDF]

open access: yesMathematische Zeitschrift, 2013
We study various classes of real hypersurfaces that are not embeddable into more special hypersurfaces in higher dimension, such as spheres, real algebraic compact strongly pseudoconvex hypersurfaces or compact pseudoconvex hypersurfaces of finite type. We conclude by stating some open problems.

Chirality of Real Non-singular Cubic Fourfolds and Their Pure Deformation Classification [PDF]

open access: yes, 2019
In our previous works we have classified real non-singular cubic hypersurfaces in the 5-dimensional projective space up to equivalence that includes both real projective transformations and continuous variations of coefficients preserving the ...

The computation of the index of a Morse function at a critical point

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
A theoretical approach in computing the index of a Morse function at a critical point on a real non-singular hypersurface V is given. As a consequence the Euler characteristic of V is computed. In the case where the hypersurface is polynomial and compact,

On the Ricci tensor of real hypersurfaces of quaternionic projective space

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
We study some conditions on the Ricci tensor of real hypersurfaces of quaternionic projective space obtaining among other results an improvement of the main theorem in [9].
