## Abstract

We show here how it is possible to build a QFT on the horizon of a Schwarzschild-like spacetime. That theory, found by restricting bulk quantum elds on the horizon, is equivalent to QFT on the bulk. That fact is called Holography. Moreover the hidden conformal symmetry (SL(2;R)) found for the bulk theory becomes manifest on the horizon in terms of some of its dieomorphisms. Then the extension of group of the generator of that symmetry to the Virasoro algebra is discussed.
