GENERAL PROBLEMS IN THE THEORY OF TRANSFER

A study has been made of equilibrium temperature fluctuations of molecular and photon gases in a cavity that is bounded by a cylindrical surface and is in a condensed medium with a high thermal conductivity. It has been shown that the indicated fluctuations belong to the class of non-Markovian random processes and require stochastic integral equations for their description. Basic statistical characteristics of the change in the cavity temperature, including characteristic functions and spectral densities of fluctuation power, have been determined.
