      Falcón Ganfornina, Raúl Manuel; Núñez Valdés, Juan (Hadronic Press, 2006)
      Due to a mathematical necessity, it has been proved that it is convenient to give a new interpretation of the multiplicity of Santilli's isounity Ib = Ib(x, v, t, µ, ρ, ...) of any Santilli's isotopism, as a family of ...

      A particular type of non-associative algebras and graph theory  [Presentation]

      Núñez Valdés, Juan; Silvero Casanova, Marithania; Villar Liñán, María Trinidad (World Scientific and Engineering Academy and Society Press, 2011)
      Evolution algebras have many connections with other mathematical fields, like group theory, stochastics processes, dynamical systems and other related ones. The main goal of this paper is to introduce a novel non-usual ...

      ¿Alcanzaría siquiera a pensar Hilbert que la resolución del décimo de los problemas por él planteados podría venir de la mano de una mujer? : Julia Robinson  [Presentation]

      Núñez Valdés, Juan; Hernández Fernández, Isabel; Mateos Contreras, Consuelo (Unidad para la Igualdad, Universidad de Sevilla, 2009)
      La educación femenina a finales del siglo XIX y principios del XX estaba muy abandonada en casi todos los países y de manera mucho más acusada en España. Fuera del aprendizaje de las “cuatro reglas”, el acceso de la mujer ...

      Algebraic computation of genetic patterns related to three-dimensional evolution algebras  [Article]

      Falcón Ganfornina, Óscar Jesús; Falcón Ganfornina, Raúl Manuel; Núñez Valdés, Juan (Elsevier, 2018-02-15)
      The mitosis process of an eukaryotic cell can be represented by the structure constants of an evolution algebra. Any isotopism of the latter corresponds to a mutation of genotypes of the former. This paper uses Computational ...

      An algorithm to compute abelian subalgebras in linear algebras of upper-triangular matrices  [Article]

      Ceballos González, Manuel; Núñez Valdés, Juan; Tenorio Villalón, Ángel Francisco (American Institute of Physics, 2009)
      This paper deals with the maximal abelian dimension of the Lie algebra hn, of nxn upper-triangular matrices. Regarding this, we obtain an algorithm which computes abelian subalgebras of hn as well as its implementation ...

      An Application of Total-Colored Graphs to Describe Mutations in Non-Mendelian Genetics  [Article]

      Falcón Ganfornina, Raúl Manuel; Falcón Ganfornina, Óscar Jesús; Núñez Valdés, Juan (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 ...

      An approach to the isotheory by means of extended pseudoisotopisms  [Article]

      Falcón Ganfornina, Raúl Manuel; Núñez Valdés, Juan (American Institute of Physics, 2016)
      Based on the traditional concept of isotopism, extended isotopisms were introduced by the authors in 2006 in order to provide a fundamental basis to the isotheory of Santilli. Since that first attempt, distinct studies on ...
