Canonical liftings of Calabi–Yau hypersurfaces: Dwork hypersurfaces

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

Willmore-type variational problem for foliated hypersurfaces

open access: yesElectronic Research Archive
After Thomas James Willmore, many authors were looking for an immersion of a manifold in Euclidean space or Riemannian manifold, which is the critical point of functionals whose integrands depend on the mean curvature or the norm of the second ...

Hyperbolicity of Projective Hypersurfaces

open access: yes, 2016
This book presents recent advances on Kobayashi hyperbolicity in complex geometry, especially in connection with projective hypersurfaces. This is a very active field, not least because of the fascinating relations with complex algebraic and arithmetic geometry. Foundational works of Serge Lang and Paul A.

On the curvates of the parallel hypersurfaces

open access: yesCommunications, Faculty Of Science, University of Ankara Series A1Mathematics and Statistics, 1992
Theorems which concern \(i\)-th mean curvatures, \(1\leq i\leq n-1\), of an hypersurface \(M\) of \(E^n\) and principal curvatures of a parallel hypersurface \(M_r\) of \(M\) are proved. Among them is a generalization in \(E^n\) of a well-known theorem of Bonnet for parallel hypersurfaces in \(E^3\).

A note about almost contact metric hypersurfaces axioms for almost Hermitian manifolds

open access: yesДифференциальная геометрия многообразий фигур
From 1950s, it is known that an almost contact metric structure is in­duced on an arbitrary oriented hypersurface in an almost Hermitian mani­fold. In accordance with the definition, an almost Hermitian manifold satisfies the axiom of almost contact ...
