      Leibniz algebras associated with representations of filiform Lie algebras  [Article]

      Ayupov, Sh. A.; Camacho Santana, Luisa María; Khudoyberdiyev, Abror Kh.; Omirov, Bakhrom Abdazovich (Elsevier, 2015)
      In this paper we investigate Leibniz algebras whose quotient Lie algebra is a naturally graded filiform Lie algebra nn,1. We introduce a Fock module for the algebra nn,1 and provide classification of Leibniz algebras L ...

      Leibniz algebras constructed by Witt algebras  [Article]

      Camacho Santana, Luisa María; Omirov, Bakhrom Abdazovich; Kurbanbaev, T.K. (Taylor and Francis, 2018)
      We describe infinite-dimensional Leibniz algebras whose associated Lie algebra is the Witt algebra and we prove the triviality of low-dimensional Leibniz cohomology groups of the Witt algebra with the coefficients in itself.

      Calderón, Antonio J.; Camacho Santana, Luisa María; Omirov, Bakhrom Abdazovich (Elsevier, 2016)
      We introduce and provide a classification theorem for the class of Heisenberg-Fock Leibniz algebras. This category of algebras is formed by those Leibniz algebras L whose corresponding Lie algebras are Heisenberg algebras ...

      Leibniz Algebras Whose Semisimple Part is Related to sl2  [Article]

      Camacho Santana, Luisa María; Gómez Vidal, S.; Omirov, Bakhrom Abdazovich; Karimjanov, I. A. (Springer, 2017)
      In this paper we identify the structure of complex finite-dimensional Leibniz algebras with associated Lie algebras sl1 2⊕sl2 2⊕· · ·⊕sls 2⊕R, where R is a solvable radical. The classifications of such Leibniz algebras ...

      Leibniz algebras with associated Lie algebras sl_2\dot{+} R (dim R=2)  [Article]

      Camacho Santana, Luisa María; Gómez Vidal, S.; Omirov, Bakhrom Abdazovich (Cornell University, 2011)
      From the theory of finite dimensional Lie algebras it is known that every finite dimensional Lie algebra is decomposed into a semidirect sum of semisimple subalgebra and solvable radical. Moreover, due to work of ...

      Local refinement based on the 7-triangle longest-edge partition  [Article]

      Plaza, Ángel; Márquez Pérez, Alberto; Moreno González, Auxiliadora; Suárez, José P. (2009)
      The triangle longest-edge bisection constitutes an efficient scheme for refining a mesh by reducing the obtuse triangles, since the largest interior angles are subdivided. In this paper we specifically introduce a new local ...

      Locally grid graphs: classification and Tutte uniqueness  [Article]

      Márquez Pérez, Alberto; Mier, Anna de; Noy, Marc; Revuelta Marchena, María Pastora (2003)
      We define a locally grid graph as a graph in which the structure around each vertex is a 3×3 grid ⊞, the canonical examples being the toroidal grids Cp×Cq. The paper contains two main results. First, we give a complete ...

      Locating Two Transfer Points on a Network with a Trip Covering Criterion and Mixed Distances  [Article]

      López de los Mozos Martín, María Cruz; Mesa López-Colmenar, Juan Antonio; Schöbel, Anita (Cornell University, 2013)
      In this paper we consider a set of origin-destination pairs in a mixed model in which a network embedded in the plane represents an alternative high-speed transportation system, and study a trip covering problem which ...

      Locating waste pipelines to minimize their impact on marine environment  [Article]

      Cáceres Sansaloni, María Teresa; Mesa López-Colmenar, Juan Antonio; Ortega Riejos, Francisco Alonso (Elsevier, 2007)
      A waste pipeline, considered as an undesirable facility, is to be located in a coastal region. Two criteria are taken into account, the Euclidean distance from a given set of protected areas (coral reefs and sandbanks) ...

      Long-Term Stability Estimates and Existence of a Global Attractor in a Finite Element Approximation of the Navier–Stokes Equations with Numerical Subgrid Scale Modeling  [Article]

      Badia, Santiago; Codina, Ramón; Gutiérrez Santacreu, Juan Vicente (SIAM, 2010)
      Variational multiscale methods lead to stable finite element approximations of the Navier–Stokes equations, dealing with both the indefinite nature of the system (pressure stability) and the velocity stability loss for ...

      Mathematical foundations of Santilli isotopies  [Article]

      Falcón Ganfornina, Raúl Manuel; Núñez Valdés, Juan; Aversa, Alan (Hadronic Press, 2015)
      The main objective of this text is to present the most basic and fundamental aspects of the isotopic Lie-Santilli theory, more commonly known as Lie-Santilli isotheory or simply isotheory, for short. To achieve this goal, ...

      Membrane parallelism for discrete Morse theory applied to digital images  [Article]

      Reina Molina, Raúl; Díaz Pernil, Daniel; Real Jurado, Pedro; Berciano Alcaraz, Ainhoa (2015)
      In this paper, we propose a bio-inspired membrane computational framework for constructing discrete Morse complexes for binary digital images. Our approach is based on the discrete Morse theory and we work with cubical ...

      Miscellaneous properties of embeddings of line, total and middle graphs  [Article]

      Boza Prieto, Luis; Dávila de Tena, María Teresa; Márquez Pérez, Alberto; Moyano Franco, Rafael (2001)
      Chartrand et al. (J. Combin. Theory Ser. B 10 (1971) 12–41) proved that the line graph of a graph G is outerplanar if and only if the total graph of G is planar. In this paper, we prove that these two conditions are ...
