    • Generic behaviour of asymptotically holomorphic Lefschetz pencils 

      Amorós Torrent, Jaume; Muñoz, Vicente; Presas, Francisco (World Scientific, 2005)
      Article
      Accés obert
      We prove that the vanishing spheres of the Lefschetz pencils constructed by Donaldson on symplectic manifolds of any dimension are conjugated under the action of the symplectomorphism group of the fiber. More precisely, ...

    • Grid equivalent representation of power systems with penetration of power electronics 

      Song, Jie; Cheah Mañé, Marc; Prieto Araujo, Eduardo; Amorós Torrent, Jaume; Gomis Bellmunt, Oriol (Institute of Electrical and Electronics Engineers (IEEE), 2023-03-13)
      Article
      Accés obert
      The Thévenin equivalent is considered as the standard grid equivalent for power system analysis. The integration on power electronics components in the power systems introduces non-linear operation characteristics that ...

      Amorós Torrent, Jaume (Societat Catalana de Matemàtiques (SCM), 2003-07)
      Article
      Accés obert
      La biblioteca matemàtica digital és un somni, que ha esdevingut un projecte gràcies als avenços de la tecnologia informàtica dels darrers anys.

    • Les revistes matemàtiques catalanes es digitalitzen del tot

    • Matter Bounce Scenario in F(T) gravity 

      Haro Cases, Jaume; Amorós Torrent, Jaume (2016)
      Article
      Accés obert
      It is shown that teleparallel F(T) theories of gravity combined with holonomy corrected Loop Quantum Cosmology (LQC) support a Matter Bounce Scenario (MBS) which is a potential alternative to the inflationary paradigm. The ...

    • Monodromía geométrica en familias de curvas de género 4 

      Amorós Torrent, Jaume; Berna Sepúlveda, Isabel (2012)
      Capítol de llibre
      Accés obert
      The geometric mono dromy of a family of complex pro jective curves is equiv- alent to the mono dromy in the fundamental group of the b ers. When the family is one of branched covers of the pro jective line this mono ...

    • Morse cell decomposition and parametrization of surfaces from point clouds 

      Alberich Carramiñana, Maria; Amorós Torrent, Jaume; Coltraro, Franco; Torras, Carme; Verdaguer López, Miquel (Publicacions de la Universitat Jaume I, 2022)
      Text en actes de congrés
      Accés obert
      An algorithm for the reconstruction of a surface from a point sample is presented. It proceeds directly from the point-cloud to obtain a cellular decomposition of the surface derived from a Morse function. No intermediate ...

    • Nonsingular models of universes in teleparallel theories 

      Haro Cases, Jaume; Amorós Torrent, Jaume (2013-02-14)
      Article
      Accés obert
      Different models of universes are considered in the context of teleparallel theories. Assuming that the universe is filled by a fluid with an equation of state P ¼ f ð Þ , for different teleparallel theories ...

      Article
      Accés obert
      This work contains a detailed qualitative analysis, in general relativity and in loop quantum cosmology, of the dynamics in the associated phase space of a scalar field minimally coupled with gravity, whose potential mimics ...

    • R+aR2 loop quantum cosmology

      Article
      Accés obert
      Working in Einstein frame, we introduce, in order to avoid singularities, holonomy corrections to the f(R)=R+aR2 model. We perform a detailed analytical and numerical study when holonomy corrections are taken into account ...
