New examples of generalized Sasakian-space-forms
(Università di Torino, 2015)
In this paper we study when a non-anti-invariant slant submanifold of a generalized Sasakian-space-form inherits such a structure, on the assumption that it is totally geodesic, totally umbilical, totally contact geodesic ...

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 ...

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.

Submanifolds of generalized Sasakian space forms
(Mathematical Society of the Republic of China, 2009-06)
In the present paper submanifolds of generalized Sasakian-spaceforms are studied. We focus on almost semi-invariant submanifolds, these generalize invariant, anti-invariant, and slant submanifolds. Sectional curvatures, ...

Some special types of developable ruled surface
(Hacettepe University (Faculty of Science), 2010)
In this study we consider the focal curve Cγ of a space curve γ and its focal curvatures. We characterize some special types of ruled surface, choosing one of the base curves or director curves as the focal curve of the ...

B.-Y. Chen's inequality for submanifolds of generalized space forms
(Indian National Science Academy, 2007-06)
In this article, we investigate sharp inequalities involving δ-invariants for submanifolds in both generalized complex space forms and generalized Sasakian space forms, with arbitrary codimension.

A closed form for slant submanifolds of generalized Sasakian space forms
(MDPI, 2019-12-13)
The Maslov form is a closed form for a Lagrangian submanifold of Cm, and it is a conformal form if and only if M satisfies the equality case of a natural inequality between the norm of the mean curvature and the scalar ...

Bi-slant submanifolds of para Hermitian manifolds
(MDPI, 2019-07-11)
In this paper, we introduce the notion of bi-slant submanifolds of a para Hermitian manifold. They naturally englobe CR, semi-slant, and hemi-slant submanifolds. We study their first properties and present a whole gallery ...
