Desigualdades de Penrose e um teorema da massa positiva para buracos negros carregados / Penrose inequalities and apositive mass theorem for charged black roles

Weslley Marinho LozÃrio 24 February 2014 (has links)
CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / Apresentamos desigualdades do tipo Penrose e um teorema de massa positiva para buracos negros carregados, isto Ã, dados iniciais para soluÃÃes tempo-simÃtricas das equaÃÃes de Einstein-Maxwell, que podem ser isometricamente mergulhados no espaÃo euclidiano como grÃficos. As demonstraÃÃes usam uma fÃrmula integral para massa ADM de tais hipersuperfÃcies e o fluxo pela curvatura mÃdia inversa. / We present Penrose-type inequalities and a positive mass theorem to charged black roles, ie, initial data for time-symmetric solutions of the Einstein-Maxwell equations, which can be isometrically immersed in Euclidean space as graphics. The statements use an integral formula for the ADM mass of such hypersurfaces and the inverse mean curvature flow.
