Abstract
The spectral representation of the mass operator at zero temperature is generalized to the case of an arbitrary temperature. For convenience, retarded and advanced Green functions are used because they possess simple analytic properties at any temperature. In a iike manner, photon or phonon retarded or advanced Green functions are used to define the polarization operator. (H.D.R.)
