      Cellular Skeletons: A New Approach to Topological Skeletons with Geometric Features  [Article]

      González Lorenzo, Aldo; Bac, Alexandra; Mari, Jean-Luc; Real Jurado, Pedro (2015)
      This paper introduces a new kind of skeleton for binary volumes called the cellular skeleton. This skeleton is not a subset of voxels of a volume nor a subcomplex of a cubical complex: it is a chain complex together with ...

      Classification of asexual diploid organisms by means of strongly isotopic evolution algebras defined over any field  [Article]

      Falcón Ganfornina, Óscar Jesús; Falcón Ganfornina, Raúl Manuel; Núñez Valdés, Juan (Elsevier, 2017-02-15)
      Evolution algebras were introduced into Genetics to deal with the mechanism of inheritance of asexual organisms. Their distribution into isotopism classes is uniquely related with the mutation of alleles in nonMendelian ...

      Combinatorial proof for a stability property of plethysm coefficients  [Article]

      Colmenarejo Hernando, Laura; Briand, Emmanuel (Elsevier, 2014)
      Plethysm coefficients are important structural constants in the representation the- ory of the symmetric groups and general linear groups. Remarkably, some sequences of plethysm coefficients stabilize (they are ultimately ...
