An eigenvalue estimate for self-shrinkers in a Ricci shrinker

Advanced Nonlinear Studies
In this paper, we study the drifted Laplacian Δf on a hypersurface M in a Ricci shrinker (M̄,g,f) $\left(\bar{M},g,f\right)$ . We prove that the spectrum of Δf is discrete for immersed hypersurfaces with bounded weighted mean curvature in a Ricci ...

Homology of T-Hypersurfaces

, 2023
Notre objet d’étude est la topologie, en particulier l’homologie, des T-hypersurfaces. Ces espaces topologiques construits de manière combinatoire sont une généralisation des patchworks combinatoires d’O. Viro.

On some almost contact metric hypersurfaces of W4-manifolds

Дифференциальная геометрия многообразий фигур, 2018
It is proved that 3-hypersurfaces of W4-manifolds admit an almost contact metric structures that can be identical to the structure induced on 2-hypersurfaces of such manifolds.

Some remarks on tight hypersurfaces

, 1991
SynopsisWe study the outer part of tight hypersurfaces. We explore in detail how the outer part of such hypersurfaces for n ≧ 3 is more complicated than in the case of tight surfaces in R3.

Compact Dupin Hypersurfaces

, 2021
A hypersurface M in Rn is said to be Dupin if along each curvature surface, the corresponding principal curvature is constant. A Dupin hypersurface is said to be proper Dupin if the number of distinct principal curvatures is constant on M, i.e., each ...

Canonical liftings of Calabi–Yau hypersurfaces: Dwork hypersurfaces

manuscripta mathematica
Abstract We explicitly compute canonical liftings modulo $$p^2$$ p 2 in a sense of Achinger–Zdanowicz of Dwork hypersurfaces.

Manifolds with integrable affine shape operator

Le Matematiche, 2005
This work establishes the conditions for the existence of vector fields with the property that theirs covariant derivative, with respect to the affine normal connection, be the affine shape operatorS in hypersurfaces.
