Symmetry Transformations in Cosmological and Black Hole Analytical Solutions
Edgar A. León, Andrés Sandoval-RodrÃguez
We analyze the transformation of a very broad class of metrics that can be expressed in terms of static coordinates. Starting from a general ansatz, we obtain a relation for the pa…

Beyond Schwarzschild: New Pulsating Coordinates for Spherically Symmetric Metrics
E. A. León, J. A. Nieto, A. Sandoval-RodrÃguez +1
Starting from a general transformation for spherically symmetric metrics where g\_11=-1/g\_00, we analyze coordinates with the common property of conformal flatness at constant sol…
