Bose condensation is characterized by a condition on the zero-frequency fourier component of the self-energy at the critical value of the chemical potential. This condition is used to show that under the action of an external linear perturbation the k = 0 mode goes over into a coherent state in the
Dielectric relaxation phenomena are analyzed wil.h an exactly solvable model. This is such a general model that it includes typical stochastic processes and models as special cases. The solutions in the frequency domain as well as in the time domain are obtained and dielectric function e(w) is expli
