Scientific paper

Information on the statistical properties of the high energy emission from Active Galactic Nuclei (AGN's) can be derived assuming that they contribute to the Cosmic Diffuse Background (CDB) in the 200 keV to 20 MeV energy range. Gamma-ray number-flux relations for AGN's are computed. They are based on their X-ray luminosity function, and different assumptions on their spectral shape and cosmological evolution are made. The limit on their integrated emissivity poses some constraints on the possible spectral shape and evolution of AGN's at hard X-ray/gamma-ray energy. The derived constraints are discussed.
