Divided into four parts, this book covers recent developments in topics pertaining to gravity theories, including discussions on the presence of scalar fields.
Part One is devoted to exact solutions in general relativity, and is mainly concerned with the results of rotating null dust beams and fluids. Also included is a panoramic vision of new research directions in this area, which would require revising certain theorems and their possible extensions within gravity theories, new aspects concerning the Ernst potentials, double Kerr spacetimes, and rotating configurations. In particular,...

The world has entered a period of significant changes regarding the future of energy generation, mainly caused by the apparent exhaustion of hyd- carbons in the near future, and the Greenhouse gases (GHG) effect of alt- ing the climate worldwide. Mexico, as a developing country, and as the eleventh-most populated nation with the thirteenth-largest territory, and as the owner of important oil production resources, is a good example of a State needing to improve and increase its energy generation. A concerted action amongst the e- nomic sectors involved both governmental and industrial could...
