A Moser–Bernstein problem for Riemannian warped products
Albujer, Alma L.; Herrera, Jónatan; Rubio, Rafael (Springer, 2020)In this work we deal with an elliptic non-linear problem, which arises naturally from Riemannian geometry. This problem has classically been studied in the the Euclidean n-dimensional space and it is known as the Moser–Bernstein ... -
Infinitesimal relative position vector fields for observers in a reference frame and applications to conformally stationary spacetimes
Caballero, Magdalena; De la Fuente, Daniel; Rubio, Rafael (Springer, 2019)We introduce and analyze the concept of infinitesimal relative position vector field between “infinitesimally nearby” observers, showing the equivalence between different definitions. Through the Fermi–Walker derivative ... -
Relativistic particles with torsion in three-dimensional non-vacuum spacetimes
Herrera, Jónatan; Rosa, M. de la; Rubio, Rafael (American Institute of Physics, 2021)In this paper, we analyze trajectories of spacelike curves that are critical points of a Lagrangian depending on its total torsion. We focus on two important families of spacetimes, generalized Robertson–Walker and standard ...
