On the necessary and sufficient conditions for the convergence of the difference schemes for the general boundary value problem for the linear systems of ordinary differential equations
We consider the numerical solvability of the general linear boundary value problem for the systems of linear ordinary differential equations. Along with the continuous boundary value problem we consider the sequence of the general discrete boundary value problems, i.e. the corresponding general difference schemes. We establish the effective necessary and sufficient (and effective sufficient) conditions for the convergence of the schemes. Moreover, we consider the stability of the solutions of general...

On the number of zeros of bounded nonoscillatory solutions to higher-order nonlinear ordinary differential equations
The higher-order nonlinear ordinary differential equation is considered and the problem of counting the number of zeros of bounded nonoscillatory solutions satisfying is studied. The results can be applied to a singular eigenvalue problem.
