  • Weierstrass per ell mateix: alguns trets del seu pensament matemàtic 

    Massa Esteve, Maria Rosa (2015-03-25)
    External research report
    Open Access
    El coneixement de Karl Weierstrass (1815-1897) a través dels teoremes que s’estudien a les classes de matemàtiques ens aporta una visió parcial del personatge. En aquesta ponència es pretén enriquir aquesta visió apropant-nos ...
  • Hamilton-Jacobi theory in multisymplectic classical field theories 

    de León, Manuel; Prieto Martínez, Pedro Daniel; Román Roy, Narciso; Vilariño, Silvia (2015-04-08)
    External research report
    Open Access
    The geometric framework for the Hamilton-Jacobi theory developed in [14, 17, 39] is extended for multisymplectic first-order classical field theories. The Hamilton-Jacobi problema is stated for the Lagrangian and the ...

  • On cyclic Kautz digraphs 

    Böhmová, Katerina; Dalfó Simó, Cristina; Huemer, Clemens (2015)
    External research report
    Open Access
    A prominent problem in Graph Theory is to find extremal graphs or digraphs with restrictions in their diameter, degree and number of vertices. Here we obtain a new family of digraphs with minimal diameter, that is, given ...
  • Continua of periodic points for planar integrable rational maps. 

    Gasull Embid, Armengol; Llorens, Mireia; Mañosa Fernández, Víctor (2015-11-30)
    External research report
    Open Access
    We present three alternative methodologies to find continua of periodic points with a prescribed period for rational maps having rational first integrals. The first two have been already used for other authors and apply ...

  • The conjugacy problem for free-by-cyclic groups 

    Martino, Armando; Ventura Capell, Enric (2004-04)
    External research report
    Open Access
    We show that the conjugacy problem is solvable in [finitely generated free]-by-cyclic groups, by using a result of O. Maslakova that one can algorithmically find generating sets for the fixed sub- groups of free group ...
  • Bisemivalues, binomial bisemivalues and multilinear extension for bicooperative games 

    Domènech Blázquez, Margarita; Giménez Pradales, José Miguel; Puente del Campo, María Albina (2015-10-05)
    External research report
    Open Access
    We introduce bisemivalues for bicooperative games and we also provide an interesting characterization of this kind of values by means of weighting coefficients in a similar way than given for semivalues in the context of ...
