Expanders and right-angled Artin groups
(World Scientific Publishing Company, 2021)
The purpose of this paper is to give a characterization of families of expander graphs via right-angled Artin groups. We prove that a sequence of simplicial graphs {Γi}i∈N forms a family of expander graphs if and only ...

Classifications of evolution algebras over finite fields
(2016-01)
In this communication we deal with a class of emerging algebras called evolution algebras. These algebras were firstly introduced by J. P. Tian, and then jointly presented with Vojtechovsky in 2006 [6], and later appeared ...

Distribution of low dimensional Malcev algebras over finite fields into isomorphism and isotopism classes
(2015)
This paper addresses the distribution into isomorphism and isotopism classes of the set Mn,p of n-dimensional Malcev algebras over the finite field Fp, with p prime. This distribution is explicitly determined for dimension ...

Un paseo fotográfico por la vida de Sophus Lie
(Sociedad Colombiana de Matemáticas, 2010)
It is quite a lot scarce the literature on the Norwegian mathematician Sophus Lie, in spite of being him, as the great volume of his works demonstrates, one of the most important mathematicians throughout the history. In ...

Estudio de la Isotopología de Tsagas-Sourlas-Santilli
(Hadronic Press, 2003)
Since his original proposal of 1978 to study Lie-isotopic and Lie-admissible liftings of conventional, local-differential Hamiltonian formulations of point particles, the physicist R. M. Santilli suggested the contribution ...

Directed pseudo-graphs and Lie algebras over finite fields
(Institute of Mathematics, Czech Academy of Sciences, 2014-03)
The main goal of this paper is to show an application of Graph Theory to classifying Lie algebras over finite fields. It is rooted in the representation of each Lie algebra by a certain pseudo-graph. As partial results, ...

Induced structures on slant submanifolds of metric F-manifolds
(Indian National Science Academy, 2008-10)
We study whether it is possible to obtain an induced structure on a slant submanifold of a metric f-manifold. Moreover, we give conditions for any isometric immersion between two metric fmanifolds to be slant and we prove ...

On the Freudenthal extensions of proper confluent maps
(University of Houston, 2012)
In this paper we study when Freudenthal extensions of proper maps preserve the (weak, semi) confluency. Also the extensions to the Alexandroff one-point compactificaton are considered.

An Application of Total-Colored Graphs to Describe Mutations in Non-Mendelian Genetics
(MDPI, 2019)
Any gene mutation during the mitotic cell cycle of a eukaryotic cell can be algebraically represented by an isotopism of the evolution algebra describing the genetic pattern of the inheritance process. We identify any ...
