AnnotationThe linearization method is widely used for the study of nonlinear models. The article considers the question of the correctness of such a method in the case of a discrete system for which the question of stability is not solved by a linear approximation, i.e. there is a critical case. A method is proposed for estimating the deviation of the nonlinear system solution from its linearized version in the critical case of a single unit root.
