ANNOTATION
The article investigates a system of linear ordinary differential equations of the second order of a general form with a boundary singular point. A certain equation of the system is considered the main one and its study is carried out depending on the properties of the coefficient for the corresponding unknown function in this equation. The problem of solving this system is reduced to an equivalent problem of solving a system of Volterra integral equations of the second kind with a weak singularity. The general solution of the system is expressed using the resolvent system of integral equations. The obtained representation is used to establish its inversion formulas, study the behavior of solutions in the neighborhood of a singular point, the correct formulation and solving of the Cauchy problem of a new type.
