ASYMPTOTICS OF THE SOLUTION OF A TWO-POINT BOUNDARY-VALUE PROBLEM FOR A LINEAR SINGULARLY PERTURBED SYSTEM OF DIFFERENTIAL EQUATIONS IN THE CASE OF A SINGULAR BOUNDARY MATRIX PENCIL (ONE-DIMENSIONAL CASE). PART 1
摘要
By using asymptotic methods of the theory of differential equations and the method of Newton diagrams, we study the problem of construction of the asymptotic solutions of two-point boundary-value problems for linear singularly perturbed systems of differential equations in the case of a singular boundary matrix pencil that does not contain regular kernels.
