    Distinguishing graphs by their left and right homomorphism profiles  [Article]

    Garijo Royo, Delia; Goodall, Andrew; Nešetřil, Jaroslav (Elsevier, 2011)
    We introduce a new property of graphs called ‘q-state Potts unique-ness’ and relate it to chromatic and Tutte uniqueness, and also to ‘chromatic–flow uniqueness’, recently studied by Duan, Wu and Yu. We establish for ...

    Contractors for flows  [Article]

    Garijo Royo, Delia; Goodall, Andrew; Nešetřil, Jaroslav (Elsevier, 2011)
    We answer a question raised by Lovász and B. Szegedy [Contractors and connectors in graph algebras, J. Graph Theory 60:1 (2009)] asking for a contractor for the graph parameter counting the number of B-flows of a graph, ...

    On the computation of Bernstein–Sato ideals  [Article]

    Ucha Enríquez, José María; Castro Jiménez, Francisco Jesús (Elsevier, 2004)
    In this paper we compare the approach of Brianc¸onand Maisonobe for computing Bernstein–Sato ideals—based on computations in a Poincar´e–Birkhoff–Witt algebra—with the readily available method of Oaku and Takayama. We ...

    Finding multiplies solutions for non-linear integer programming  [Article]

    Jiménez Cobano, José Manuel; Ucha Enríquez, José María (Elsevier, 2018)
    We explain how to compute all the solutions of a nonlinear integer problem using the algebraic test-sets associated to some linear subproblem. These test-sets are obtained using Gr¨obner bases. We compare our method with ...

    Explicit Comparison Theorems for D -modules  [Article]

    Castro Jiménez, Francisco Jesús; Ucha Enríquez, José María (Elsevier, 2001)
    We prove in an explicit way a duality formula between two A2-modules Mlog and Mflog associated to a plane curve and we give an application of this duality to the comparison between Mflog and the A2-module of rational ...

    Totally umbilical disks and applications to surfaces in three-dimensional homogeneous spaces  [Article]

    Espinar, José M.; Fernández Delgado, Isabel (Sociedade Brasileira de Matemática, 2008)
    Following [Ch] and [dCF], we give sufficient conditions for a disk type surface, with piecewise smooth boundary, to be totally umbilical for a given Coddazi pair. As a consequence, we obtain rigidity results for surfaces ...

    The number of conformally equivalent maximal graphs  [Article]

    Fernández Delgado, Isabel (Springer, 2010)
    We show that the number of entire maximal graphs with finitely many singular points that are conformally equivalent is a universal constant that depends only on the number of singularities, namely 2n for graphs with n + ...

    The Gauss map of surfaces in PSL˜2(R)  [Article]

    Daniel, Benoit; Fernández Delgado, Isabel; Mira, Pablo (Springer, 2015)
    We define a Gauss map for surfaces in the universal cover of the Lie group PSL2(R) endowed with a left-invariant Riemannian metric having a 4-dimensional isometry group. This Gauss map is not related to the Lie group ...
