    Rodrigues, Hildebrando M.; Solà-Morales Rubió, Joan de (2017-03-15)
    Article
    Accés restringit per política de l'editorial
    Let XX be a Banach space and T¿:X¿XT¿:X¿X a family of invertible contractions, T¿=L¿+f¿T¿=L¿+f¿, where L¿L¿ is linear and f¿f¿ is nonlinear with f¿(0)=0f¿(0)=0. We give conditions for the existence of a family of global ...
  • The conjugacy problem in extensions of Thompson's group F 

    Burillo Puig, José; Matucci, Francesco; Ventura Capell, Enric (2016-10-01)
    Article
    Accés restringit per política de l'editorial
    We solve the twisted conjugacy problem on Thompson’s group F. We also exhibit orbit undecidable subgroups of Aut(F), and give a proof that Aut(F) and Aut+(F) are orbit decidable provided a certain conjecture on Thompson’s ...
  • Low-dimensional dynamics of structured random networks 

    Aljadeff, Johnatan; Renfrew, David; Vegué Llorente, Marina; Sharpee, Tatyana O. (American Chemical Society (ACS), 2016-02-05)
    Article
    Accés obert
    Using a generalized random recurrent neural network model, and by extending our recently developed mean-field approach [J. Aljadeff, M. Stern, and T. Sharpee, Phys. Rev. Lett. 114, 088101 (2015)], we study the relationship ...
  • Teleparallel loop quantum cosmology in a system of intersecting branes 

    Haro Cases, Jaume (Elsevier, 2016-09-10)
    Article
    Accés restringit per política de l'editorial
    Recently, some authors have removed the big bang singularity in teleparallel Loop Quantum Cosmology (LQC) and have shown that the universe may undergo a number of oscillations. We investigate the origin of this type of ...
  • Evolution and dynamics of a matter creation model 

    Pan, Supriya; Haro Cases, Jaume; Paliathanasis, A.; Slagter, R.J. (2016-05-01)
    Article
    Accés obert
    In a flat Friedmann–Lemaître–Robertson–Walker (FLRW) geometry, we consider the expansion of the universe powered by the gravitationally induced ‘adiabatic’ matter creation. To demonstrate how matter creation works well ...
  • Gravitationally induced adiabatic particle production: from big bang to de Sitter 

    Haro Cases, Jaume (2016-07-27)
    Article
    Accés restringit per política de l'editorial
    In the background of a flat homogeneous and isotropic space–time, we consider a scenario of the Universe driven by the gravitationally induced 'adiabatic' particle production with constant creation rate. We have shown that ...
  • On stability and controllability of multi-agent linear systems 

    García Planas, María Isabel; Tarragona, Sonia (2016-11)
    Article
    Accés obert
    Recent advances in communication and computing have made the control and coordination of dynamic network agents to become an area of multidisciplinary research at the intersection of the theory of control systems, communication ...

  • A measure of perceived performance to assess resource allocation 

    Sayeras, Josep M.; Agell, Nuria; Rovira Llobera, Xari; Sánchez Soler, Monica; Dawson, John A. (Springer, 2016-08-01)
    Article
    Accés restringit per política de l'editorial
    Performance measurement is a key issue when a company is designing new strategies to improve resource allocation. This paper offers a new methodology inspired by classic importance-performance analysis (IPA) that provides ...
  • Effect of a science communication event on students’ attitudes towards science and technology
