Gravitational Lensing by Spherical Lenses
Roger Hurtado, Leonardo Castaneda, Juan M. Tejeiro
In this work we introduced a new proposal to study the gravitational lensing theory by spherical lenses, starting from its surface mass density written in terms of a decreas…

Study of cylindrically symmetric solutions in metric f(R) gravity with constant R
Monica Tatiana Rincon-Ramirez, Leonardo Castaneda
Solutions for cylindrically symmetric spacetimes in f(R) gravity are studied. As a first approach, R=constant is assumed. A solution was found such that it is equivalent to a resul…
