Osculating hypersurfaces of higher order

open access: yesLietuvos Matematikos Rinkinys, 2011
Oscurating surfaces of second order have been studied in classical differential geometry [1]. In this article we generalize this notion to osculating hyper-surfaces of higher order of hyper-surfaces in Euclidean n-space.

Normalization of Norden — Chakmazyan for distributions given on a hypersurface

open access: yesДифференциальная геометрия многообразий фигур, 2020
In the projective space, we continue to study a hypersurface with three strongly mutual distributions. For equipping distributions of a hypersurface, normalization in the sense of Norden — Chakmazyan is introduced internally.

Implicitization of hypersurfaces

open access: yesJournal of Symbolic Computation, 2017
We present new, practical algorithms for the hypersurface implicitization problem: namely, given a parametric description (in terms of polynomials or rational functions) of the hypersurface, find its implicit equation. Two of them are for polynomial parametrizations: one algorithm, "ElimTH", has as main step the computation of an elimination ideal via ...

Euclidean hypersurfaces isometric to spheres

open access: yesAIMS Mathematics
Given an immersed hypersurface $ M^{n} $ in the Euclidean space $ E^{n+1} $, the tangential component $\boldsymbol{\omega }$ of the position vector field of the hypersurface is called the basic vector field, and the smooth function of the normal ...

Dirac’s discrete hypersurface deformation algebras [PDF]

open access: yes, 2013
The diffeomorphism symmetry of general relativity leads in the canonical formulation to constraints, which encode the dynamics of the theory. These constraints satisfy a complicated algebra, known as Dirac’s hypersurface deformation algebra. This algebra

Lightlike Hypersurfaces and Canal Hypersurfaces of Lorentzian Surfaces

open access: yesAbstract and Applied Analysis, 2014
The lightlike hypersurfaces in semi-Euclidean space are of special interest in Relativity Theory. In particular, the singularities of these lightlike hypersurfaces provide good models for the study of different horizon types. And we obtain some geometrical propositions of the canal hypersurfaces of Lorentzian surfaces.

$F$-thresholds of hypersurfaces [PDF]

open access: yesTransactions of the American Mathematical Society, 2009
19 pages; v.2: a slight modification of the argument allowed us to extend our results to the case of an arbitrary regular F-finite ring; v.3: final version, to appear in Transactions of the ...

The Orlik-Solomon model for hypersurface arrangements [PDF]

open access: yes, 2013
We develop a model for the cohomology of the complement of a hypersurface arrangement inside a smooth projective complex variety. This generalizes the case of normal crossing divisors, discovered by P.
