Subvariedades slant en s-variedades
(2005-07-15)
Las subvariedades slant constituyen un tipo importante de subvariedades, tanto en la Geometría Compleja como en la Geometría de Contacto, Dichas subvariedades tienen la propiedad de constituir una generalización de las ...

Can trans-S-manifolds be defined from the Gray-Hervella classification for almost Hermitian manifolds?
(Springer, 2022-04-30)
Recently, trans-S-manifolds have been defined as a wide class of metric f-manifolds which includes, for instance, f-Kenmotsu manifolds, S-manifolds and C-manifolds and generalize well-studied trans-Sasakian manifolds. The ...

On totally geodesic invariant submanifolds of an S-manifold
(Real Academia de Ciencias de Zaragoza, 1988)
In [1] Blair, O.E.: 1970, J. Diff. Geom. 4, (155-167), S-manifolds, which reduce in a special case to Sasakian manifolds, we redefined. In this note, a condition for an invariant submanifold of codimension greater than 2 ...

On ξ-conformally flat contact metric manifolds
(Indian National Science Academy, 1997-06)
In this paper, the notion of ξ-conformally flat on a contact metric structure is introduced and it is proved that any K-contact metric manifold is ξ-conformally flat if and only if it is an η-Einstein Sasakian manifold. ...

Minimal slant submanifolds of the smallest dimension in S-manifolds
(European Mathematical Society, 2005)
We study slant submanifolds of S-manifolds with the smallest dimension, specially minimal submanifolds and establish some relations between them and anti-invariant submanifolds in S-manifolds, similar to those ones proved ...

Critical elements of proper discrete Morse functions
(Editorial Board of Mathematica Pannonica, 2008)
The aim of this paper is to study the notion of critical element of a proper discrete Morse function defined on non-compact graphs and surfaces. It is an extension to the non-compact case of the concept of critical simplex ...

New relationships involving the mean curvature of slant submanifolds in S-space-forms
(Korean Mathematical Society, 2007)
Relationships between the Ricci curvature and the squared mean curvature and between the shape operator associated with the mean curvature vector and the sectional curvature function for slant submanifolds of an S-space-form ...

Generalized S-space-forms
(2013)
We introduce and study generalized S-space-forms. Moreover, we investigate generalized S-space-forms endowed with an additional structure and we obtain some obstructions for them to be S-manifolds

Funciones de Morse discretas sobre complejos infinitos
(2003)
Esta memoria está dedicada a la extensión para complejos simpliciales infinitos de los conceptos y resultados de la teoría de Morse discreta ya estudiados en el caso finito. En un principio, dicho estudio se centrará en ...
