    Autonomous Noetherian boundaryvalue problem in special critical case
    Computer Research and Modeling, 2011, v. 3, no. 4, pp. 337-351

    The necessary and sufficient terms of solution existence of nonlinear autonomous Noetherian boundary-value problem are found in special critical case. The characteristic feature of the set problems is impossibility of direct application of traditional research schematic representation and construction of solutions of critical boundary-value problems, which was created in works of I.G. Malkin, A.M. Samoilenko, E.A. Grebenikov, Yu.A. Ryabov and A.A. Boichuk. For the solution construction of Noetherian boundary-value problem in special critical case an iterative procedure is recommended, it is constructed according to the scheme of least-squares method. Efficiency of the offered technique is shown on the example of analysis for periodic problems for Hill equation.

    Periodic boudary-value problem for Hill's equation in the case of parametric resonance
    Computer Research and Modeling, 2014, v. 6, no. 1, pp. 27-43

    Necessary and sufficient conditions for the existence of solutions of nonlinear nonautonomous periodic problem for Hill’s equation in the case of parametric resonance. A characteristic feature of the task is the need of finding, as desired solution, and the corresponding eigenfunction, which ensures solvability of the periodic problem for Hill’s equation in the case of parametric resonance. To construct solutions of the periodic problem for Hill’s equation and the corresponding eigenfunction in the case of parametric resonance proposed iterative scheme, based on the method of simple iterations with used list-square technics.

    Keywords: nonlinear nonautonomous periodic boudary-value problem, Hill’s equation, the case of parametric resonance, he method of simple iterations.
