Abstract

In this paper uniform approximations are investigated for solving singularly-perturbed system of  differential equations. Initially problem of Cauchy for singular perturbed system of ordinary differential equations in the case of change of stability is considered. The diagonal matrix has complex conjugate eigenvalues, they are hyperbolic functions. A singular domain is determined and an estimate is obtained on this area. The proximity of the solution of perturbed and undisturbed problem is proved.
