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 ...

Generalized Sasakian Space Forms Which Are Realized as Real Hypersurfaces in Complex Space Forms
(MDPI, 2020-05-29)
We prove a classification theorem of the generalized Sasakian space forms which are realized as real hypersurfaces in complex space forms.

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 ...

The curvature tensor of (κ,μ,ν)-contact metric manifolds
(Springer, 2015-07)
We study the Riemann curvature tensor of (κ, µ, ν)-contact metric manifolds, which we prove to be completely determined in dimension 3, and we observe how it is affected by Da-homothetic deformations. This prompts the ...

A computational algebraic geometry approach to enumerate Malcev magma algebras over finite fields
(Wiley, 2016)
The set of Mn(K) of n-dimensional Malcev magma algebras over a finite field can be identified with algebraic sets defined by zero-dimensional radical ideals for which the computation of their reduced Gröbner bases makes ...

Using the Evolution Operator to Classify Evolution Algebras
(MDPI, 2021-08-05)
Evolution algebras are currently widely studied due to their importance not only “per se” but also for their many applications to different scientific disciplines, such as Physics or Engineering, for instance. This paper ...

On the idempotency of some composite functors
(Springer, 2012-01)
We present examples of localization functors whose composition with certain cellularization functors is not idempotent, and vice versa.

Las mujeres en la escuela pitagórica
(Sociedad Argentina de Educación Matemática, 2011-05)
En este artículo se comenta la obra matemática de las mujeres que formaban parte de la Escuela Pitagórica entre los años 600 y 500 a.C. y la gran importancia que tuvieron estas mujeres para el desarrollo tanto científico ...

Lusternik-Schnirelmann category of simplicial complexes and finite spaces
(Elsevier, 2015-10)
In this paper we establish a natural definition of Lusternik-Schnirelmann category for simplicial complexes via the well known notion of contiguity. This simplicial category has the property of being invariant under strong ...
