Soluções de p-branas e buracos negros em teorias de supergravidade.

Abstract

The present work aimed at to investigate solutions of black hole type via equations of first order considering firstly the vacuum solution in which only the gravitational field plays a significant role. In High Energy Physics, the black holes theories in supergravity play a key role in the analysis and understanding of quantum gravity. Thus, a general solution obtained for solving situations involving static black holes with mass and no electric charge was used. It was found that the scalar potential V(f) found via general solution, given in terms of superpotencial W, took different forms for different values of the parameter α present in the f term, mainly for values of α -1, taking into account that for this case graphs that describe the phase transitions of first and second order were obtained.
