    • Homothetic motions and Newtonian cosmology 

      Jaen Herbera, Javier; Molina Compte, Alfred (2014-05-07)
      Article
      Accés restringit per política de l'editorial
      We construct a homothetic covariant Newtonian gravitation theory which unifies inertial homothetic forces and gravitational fields. This is achieved through an equivalence principle based on a local homothetic frame of ...

    • On the meaning of Painlevé–Gullstrand synchronization 

      Jaen Herbera, Javier; Molina Compte, Alfred (2015-11-19)
      Article
      Accés obert
      Following on from two recent papers, here we examine the relationship between Newtonian gravitation and general relativity in more depth. This allows us to define a scalar potential which is just the proper time of the ...

    • Rigid covariance as a natural extension of Painleve-Gullstrand space-times: gravitational waves 

      Jaen Herbera, Javier; Molina Compte, Alfred (2017-08-01)
      Article
      Accés obert
      The group of rigid motions is considered to guide the search for a natural system of space-time coordinates in General Relativity. This search leads us to a natural extension of the space-times that support Painlevé–Gullstrand ...

    • Rigid motions and generalized Newtonian gravitation 

      Jaen Herbera, Javier; Molina Compte, Alfred (2013-08-01)
      Article
      Accés restringit per política de l'editorial
      In an effort to contribute to a better understanding of General Relativity, here we lay the foundations of generalized Newtonian gravity, which unifies inertial forces and gravitational fields. We also formulate a kind ...
