Relativistic versus Newtonian frames: emission coordinates
J. -F. Pascual-Sánchez, A. San Miguel, F. Vicente
Only a causal class among the 199 Lorentzian ones, which do not exists in the Newtonian spacetime, is privileged to construct a generic, gravity free and immediate (non retarded) r…
Curvature(s) of a light wavefront in a weak gravitational field
J. -F. Pascual-Sánchez, A. San Miguel, F. Vicente
The geometry of a light wavefront evolving from a flat wavefront under the action of weak gravity field in the 3-space associated to a post-Newtonian relativistic spacetime, is stu…
Numerical treatment of the light propagation problem in the post-Newtonian formalism
A. San Miguel, F. Vicente, J. -F. Pascual-Sanchez
The geometry of a light wavefront, evolving from a initial flat wavefront in the 3-space associated with a post-Newtonian relativistic spacetime, is studied numerically by means of…
Geometry of an accelerated rotating disk
J. -F. Pascual-Sánchez, A. San Miguel, F. Vicente
We analyze the geometry of a rotating disk with a tangential acceleration in the framework of the Special Theory of Relativity, using the kinematic linear differential system that…
