Abstract

In this talk I presented a previously published work concerning the evaporation of (4+n)-dimensional non-rotating black holes into gravitons. In this work we calculated the energy emission rate for gravitons in the bulk obtaining analytical solutions of the master equation satisfied by all three types (S,V,T) of gravitational perturbations and presented graphs for the absorption probability and the energy emission of the black hole in the bulk.
