Abstract: An analysis is made of a decoupling procedure in the equations of motion method for twotime temperature-dependent Green's functions. A proposal is made to estimate the accuracy of the decoupling on the basis of diagrammatic analysis of the truncated Dyson equation for the causal Green's function. The treatment is based on the example of an anharmonic lattice with allowance for the anharmonic terms of all orders.
