  • Periodic orbits of discrete and continuous dynamical systems via Poincaré-Miranda theorem 

    Gasull Embid, Armengol; Mañosa Fernández, Víctor (2018-09-17)
    Report de recerca
    Accés obert
    We present a systematic methodology to determine and locate analytically isolated periodic points of discrete and continuous dynamical systems with algebraic nature. We apply this method to a wide range of examples, including ...
  • Group inverse of the laplacian of connections of networks 

    Gago Álvarez, Silvia (2018-03-25)
    Report de recerca
    Accés restringit per política de l'editorial
    In previous works the group inverse of a network obtained by some perturbations, as the deletion of a vertex, the addition of a new vertex, contraction of an edge, etc. is obtained in terms of the group inverse of the ...
  • Neighbor-locating colorings in graphs 

    Hernando Martín, María del Carmen; Mora Giné, Mercè; Pelayo Melero, Ignacio Manuel; Alcón, Liliana; Gutierrez, Marisa (2018-06-29)
    Report de recerca
    Accés obert
    A k -coloring of a graph G is a k -partition ¿ = { S 1 ,...,S k } of V ( G ) into independent sets, called colors . A k -coloring is called neighbor-locating if for every pair of vertices u,v belonging to the same color S ...
  • Contact structures with singularities 

    Miranda Galcerán, Eva; Oms, Cédric (2018-06-15)
    Report de recerca
    Accés obert
    We study singular contact structures, which are tangent to a given smooth hypersurface Z and satisfy certain transversality conditions. These singular contact structures are determined by the kernel of non-smooth differential ...
  • TEC Parametric Model validation and Approach to GNSS operational conditions 

    González Casado, Guillermo (2017-05-10)

  • A route to chaos in the Boros-Moll map 

    Gardini, Laura; Mañosa Fernández, Víctor; Sushko, Iryna (2018-04-18)
    Report de recerca
    Accés obert
    The Boros-Moll map appears as a subsystem of a Landen transformation associated to certain rational integrals and its dynamics is related to the convergence of them. In the paper, we study the dynamics of a one-parameter ...
  • Open problems, questions, and challenges in finite-dimensional integrable systems 

    Miranda Galcerán, Eva; Bolsinov, Alexey; Matveev, Vladimir; Tabachnikov, Sergei (2018-04-11)
    Report de recerca
    Accés obert
    The paper surveys open problems and questions related to different aspects of integrable systems with finitely many degrees of freedom. Many of the open problems were suggested by the participants of the conference ...
  • Report on the EGNSS competition after Y2 

    Sanz Subirana, Jaume; Juan Zornoza, José Miguel; Alonso Alonso, María Teresa; Povero, Gabriella (2017-05-21)
    Report de recerca

  • The geometry of E-manifolds 

    Miranda Galcerán, Eva (2018-02-09)
    Report de recerca
    Accés obert
    Motivated by the study of symplectic Lie algebroids, we study a describe a type of algebroid (called an E-tangent bundle) which is particularly well-suited to study of singular differential forms and their cohomology. ...
  • Periodic points of a Landen transformation 

    Gasull Embid, Armengol; Llorens, Mireia; Mañosa Fernández, Víctor (2018-01-12)
    Report de recerca
    Accés obert
    We prove the existence of 3-periodic orbits in a dynamical system associated to a Landen transformation previously studied by Boros, Chamberland and Moll, disproving a conjecture on the dynamics of this planar map introduced ...
  • Some manifolds of periodic orbits in the restricted three body problem 

    Gómez Muntané, Gerard; Noguera Batlle, Miquel (1984)
    Report de recerca
    Accés obert
    In the present paper we give some numerical results about natural families of periodic orbits, which emanate from limiting orbits around equilateral equilibrium points of the Restricted Three Body Problem, when the mass ...
  • Locating domination in bipartite graphs and their complements 

    Hernando Martín, María del Carmen; Mora Giné, Mercè; Pelayo Melero, Ignacio Manuel (2017-11-03)
    Report de recerca
    Accés obert
    A set S of vertices of a graph G is distinguishing if the sets of neighbors in S for every pair of vertices not in S are distinct. A locating-dominating set of G is a dominating distinguishing set. The location-domination ...
