Abstract

We will present a method for building a consistent AQFT on Schwarzschild\nspacetime for a thermal system ruled by an interacting and massive scalar\nfield, extending the methods and the results of K. Fredenhagen and F. Lindner\nvalid for the flat case. In particular we will discuss the asymptotic\nproperties of the two-point function of a thermal (KMS) state in order to\nobtain finite expectation values for the observables of the theory.\n
