La teora relatividad general es una teora del campo gravitatorio y de los sistemas de referencia generales. Los principios fundamentales introducidos en esta teora son el Principio de equivalencia, que describe la aceleracin y la gravedad como aspectos distintos de la misma realidad, la nocin de la curvatura del espaciotiempo y el principio de covariancia generalizado. La intuicin bsica de Einstein fue postular que en un punto concreto no se puede distinguir experimentalmente entre un cuerpo acelerado uniformemente y un campo gravitatorio uniforme. Desde que Einstein propuso su teora en 1916 hasta el 2007, solo se tenan 4 formulaciones lagrangianas para relatividad general, a saber EinsteinHilbert, Hilbert Palatini, CapovillaDellJacobson (CDJ) y Plebanski, las cuales discutiremos ampliamente en este trabajo. Uno de los desafos de la fsica terica en el rea de gravitacin es formular la teora cuntica de la gravedad, desafortunadamente ninguna de las teoras anteriores es renormalizable y es aqu donde gravedad nomtrica pretende resolver el problema. Es por ello que analizaremos esta nueva teora propuesta por Krasnov en el 2008.
