For the non-rotating BTZ black hole, the distributional curvature tensor field is found. It is shown to have singular parts proportional to a $\delta$-distribution with support at the origin. This singularity is related, through Einstein field equati

We apply results on symmetries of equations of motion and equivalent Lagrangians to obtain a constant of motion for a particle travelling through a viscous medium and for the damped harmonic oscillator. PACS No.: 45.20Jj

In this work we integrate Einstein-Maxwell equations for a point charge, in a coordinate system first considered by Lake. The family of solutions obtained includes various well known metrics. A free metric function acting as a gauge in the solution,

The collapse of spherically symmetric selfgravitating charged perfect fluids is formulated following a procedure developed by Gatreau. The geodesic nature of the coordinate frame lead naturally to newtonian like expressions for the exact Einstein-Max

The integration of the Einstein-Maxwell equations for a spherically symmetric distribution of collapsing charged matter, is accomplished. Comparison with a neutral corresponding solution allows us to analyse the effect of electric charge on the evolu

The integration of the Einstein-Maxwell equations for an anisotropic charged fluid sphere acting as a source of the Reissner-Nordstrom metric is considered, under the assumption of a conformally flat interior metric. The solutions asymptotically tend

A prescription originally conceived for perfect fluids is extended to the case of anisotropic pressure. The method is used to obtain exact analytical solutions of the Einstein equations for spherically-symmetric self-gravitating distribution of aniso
