MÃtricas m-quasi-Einstein em variedades compactas / m-quasi-einstein metrics on compact manifolds

Rafael Jorge Pontes DiÃgenes 17 February 2012 (has links)
Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / Nosso objetivo nesse trabalho à apresentar uma generalizaÃÃo das mÃtricas quasi-Einstein para campo de vetores suaves nÃo necessariamente gradiente, alÃm disso, apresentar algumas fÃrmulas integrais para mÃtricas quasi-Einstein gradiente definidas numa variedade compacta e como aplicaÃÃo expor trÃs resultados importantes, sendo um deles uma caracterizaÃÃo para tais classes de variedades compactas de dimensÃo dois. / Our objective in this work is to present a generalization of quasi-Einstein metrics for vector field is not necessarily smooth gradient also present some integral formulas for compact quasi-Einstein metrics defined in a compact and as application set out three important results, one being characterized such classes for a compact manifolds of dimension two.
