      Inf-Sup Stable Finite Element Methods for the Landau--Lifshitz--Gilbert and Harmonic Map Heat Flow Equations  [Article]

      Gutiérrez Santacreu, Juan Vicente; Restelli, Marco (SIAM: Society for Industrial and Applied Mathematics, 2017)
      In this paper we propose and analyze a finite element method for both the harmonic map heat and Landau–Lifshitz–Gilbert equation, the time variable remaining continuous. Our starting point is to set out a unified saddle ...

      Invariant representative cocycles of cohomology generators using irregular graph pyramids  [Article]

      González Díaz, Rocío; Ion, Adrián; Iglesias Ham, Mabel; Kropatsch, Walter G. (2011)
      Structural pattern recognition describes and classifies data based on the relationships of features and parts. Topological invariants, like the Euler number, characterize the structure of objects of any dimension. Cohomology ...

      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.

      Leibniz algebras of Heisenberg type  [Article]

      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 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 ...
