The "density-density" correlation function of conduction electrons in metalis investigated. It is shown, that the asymptotic behaviour of the CF dependson the shape and the local geometry of the Fermi surface. In particular, theexponent of power law which describes the damping of Friedel oscillations atlarge r (-4 for an isotropic Fermi gas) is determined by local geometry of theFS. The applications of the obtained results to calculations of the CF in ametal near the electron topological transition and of the RKKY exchangeintegral are considered as well.Comment: 12 pages, LaTeX, 5 figures upon request (to appear in J.Phys.:CM,  1993
