%0 Journal Article %T A relativistic action-at-a-distance description of gravitational interactions? %A Domingo J. Louis-Martinez %J Physics %D 2012 %I arXiv %R 10.1103/PhysRevD.86.045009 %X It is shown that certain aspects of gravitation may be described using a relativistic action-at-a-distance formulation. The equations of motion of the model presented are invariant under Lorentz transformations and agree with the equations of Einstein's theory of General Relativity, at the first Post-Newtonian approximation, for any number of interacting point masses. %U http://arxiv.org/abs/1205.4417v1
