Inmersiones isotrópicas pseudo-riemannianas
(2008)
La noción de inmersión isotrópica Riemanniana fue introducida por B. O Neill [O N1] quien estudió propiedades generales de esta clase de inmersiones. Estas inmersiones pueden ser consideradas como una generalización del ...

Existence and uniqueness theorem for slant immersions in Sasakian-space-forms
(Institute of Mathematics (University of Debrecen), 2001)
In this paper, we present the existence and uniqueness theorems for slant immersions into Sasakian-space-forms. By applying the first result, we prove several existence theorems for slant submanifolds. In particular, we ...

Magnetic vortex filament flows
(AIP Publishing, 2007-08)
We exhibit a variational approach to study the magnetic flow associated with a Killing magnetic field in dimension 3. In this context, the solutions of the Lorentz force equation are viewed as Kirchhoff elastic rods and ...

An obstruction to represent abelian lie algebras by unipotent matrices
(2004)
The aim of this paper is the study of abelian Lie algebras as subalgebras of the nilpotent Lie algebra gn associated with Lie groups of upper-triangular square matrices whose main diagonal is formed by 1. We also give an ...

Links among characteristically nilpotent, c-graded and derived filiform lie algebras
(2005)
The aim of this paper is to study the interconnectivity among Lie algebras that are characteristically nilpotent, derived and c-graded filiform, establishing some characterization theorems involving them. At the same ...

Some inequalities on totally real submanifolds in locally conformal Kaehler space forms
(Korean Mathematical Society, 2004)
In this article, we establish sharp relations between the sectional curvature and the shape operator and also between the k-Ricci curvature and the shape operator for a totally real submanifold in a locally conformal Kaehler ...
