This electron can be band - like or belong to a quantum well. The known dynamical Keldysh model is generalized for the case of fields with finite correlation time of fluctuations and for finite transfer frequencies of these fluctuations. In all cases we are able to perform the complete summation of all Feynman diagrams of corresponding perturbation series for the Green's function. This can be done either by the reduction of this series to some continuous fraction or by the use of the generalized Ward identity from which we can derive recurrence relations for the Green's function. In the case of a random field with finite transferred frequency there appear the interesting effects of modulation of spectral density and density of states.
