Metric f-Contact Manifolds Satisfying the (κ, μ)-Nullity Condition
(MDPI, 2020-06-02)
We prove that if the f-sectional curvature at any point of a (2n+s) -dimensional metric f-contact manifold satisfying the (κ,μ) nullity condition with n>1 is independent of the f-section at the point, then it is constant ...

Generalized (κ,μ)-space forms
(Springer, 2013-02)
Generalized (κ, µ)-space forms are introduced and studied. We examine in depth the contact metric case and present examples for all possible dimensions. We also analyse the trans-Sasakian case.

(k, µ)-Espacios de Curvatura Ø-Seccional constante generalizados
(2011)
A lo largo de los años, numerosos autores han estudiado la forma del tensor de curvatura de una variedad Riemanniana para intentar clasificarla. Buena parte de los trabajos que han aparecido sobre la materia son los que ...

Submanifolds weakly associated with graphs
(Indian Academy of Sciences, 2009-06)
We establish an interesting link between differential geometry and graph theory by defining submanifolds weakly associated with graphs. We prove that, in a local sense, every submanifold satisfies such an association, and ...

Subvariedades en espacios de curvatura Ø-seccional constante generalizados
(2005)
La curvatura de Riemann es una importante herramienta en el estudio de variedades. Así, es de sobra conocida la clasificación de los espacios de curvatura constante en función del valor de dicha curvatura. En Geometría ...

Normal approximations of regular curves and surfaces
(Faculty of Sciences and Mathematics, University of Nis, Serbia, 2015)
Bezier curves and surfaces are two very useful tools in Geometric Modeling, with many applications. In this paper, we will offer a new method to provide approximations of regular curves and surfaces by Bezier ones, with ...

On generalized Sasakian-space-forms
(2004)
We study contact metric and trans-Sasakian generalized Sasakian-space-forms. We also give some interesting examples of generalized Sasakian-space-forms by using warped products and conformal changes of metric.

Generalized S-space-forms with two structure vector fields
(De Gruyter, 2010-01)
We introduce and study generalized S-space-forms with two structure vector fields. We also present several examples of these manifolds such as certain hypersurfaces of Sasakianspace-forms, principal toroidal bundles and ...

A contact version of B.-Y. Chen's inequality and its applications to slant immersions
(Kyungpook National University, 1999)
We establish a version of B.-Y. Chen’s inequality for a submanifold of a Sasakianspace-form, tangent to the structure vector field of the ambient space. We obtain some applications and we study this inequality for slant ...
