摘要：
We examine the spectral function of the single electron Green function at finite temperature for the Tomonaga-Luttinger model which consists of a mutual interaction with only forward scattering. The spectral weight, which is calculated as a function of the frequency with fixed wave number, shows that several peaks originating in the excitation spectra of charge and spin fluctuations merge into a single peak by the increase of temperature.
