Black Holes in String Theory from p/D-branes

Abstract

p-Branes are p-dimensional extended solutions of 10-dimensional (super)string theory, particularly supergravity i.e. the massless sector, coupled to n-form gauge fields. If our 10-dimensional target space is parametrized by $(t, x_1, \dots , x_9)$, then e.g. a 5-brane can by parametrized by $(t, x_1, \dots , x_5)$, where we set the transverse coordinates $(x_6, \dots x_9)$ to zero.
