| Abstract: | The unified method of solving LDS(linear discrete system) difference equations of determinate and time varying coefficients as well as stochastic and stochastic time varying coefficients is proposed. The degenerate sequence formulae of time varying Green functions and time varying correlations are derived, and the physical significance of them is explicated. |
