ANNOTATION
In the article, a system of linear ordinary differential equations of the second order of general form with a boundary weakly singular point is investigated by reducing it to a system of Volterra integral equations of the second kind with a weak singularity. The general solution of the system is written out using the resolvent system of integral equations, which is used to establish inversion formulas of the representation, study the behavior of solutions in the neighborhood of a singular point, find out the correct formulation and a solution to a Cauchy-type problem.
KEY WORDS
