Normalization of Norden — Chakmazyan for distributions given on a hypersurface

Дифференциальная 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.

Dirac’s discrete hypersurface deformation algebras [PDF]

, 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

Convexity of 𝜆-hypersurfaces [PDF]

Proceedings of the American Mathematical Society, 2022
We prove that any n n -dimensional closed mean convex λ \lambda - hypersurface is convex if λ ≤ 0. \lambda \le 0. This generalizes Guang’s work on 2 2 -dimensional strictly mean convex λ \lambda -hypersurfaces.

Mapped Null Hypersurfaces and Legendrian Maps

, 2007
For an $(m+1)$-dimensional space-time $(X^{m+1}, g),$ define a mapped null hypersurface to be a smooth map $\nu:N^{m}\to X^{m+1}$ (that is not necessarily an immersion) such that there exists a smooth field of null lines along $\nu$ that are both tangent

The Orlik-Solomon model for hypersurface arrangements [PDF]

, 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.

Euclidean hypersurfaces isometric to spheres

AIMS 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 ...

Geometric momentum for a particle constrained on a curved hypersurface [PDF]

, 2013
The canonical quantization is a procedure for quantizing a classical theory while preserving the formal algebraic structure among observables in the classical theory to the extent possible.

Lightlike Hypersurfaces and Canal Hypersurfaces of Lorentzian Surfaces

Abstract 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.
