On some linearised quantum Boltzmann equations

Prof. Miguel Escobedo

University of Bilbao

Abstract:  We study the time behavior of the solutions of some linearisations of the homogeneous quantum Boltzmann equation for bosons around thermodynamic equilibrium. We first consider the case where the gas is above the critical temperature. Then we study the case where the gas is below the critical temperature, so in presence of condensate, but the temperature is not too low. We provide in both cases the precise behavior of the solutions.
