    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.

    The modified twosweep iteration technique for the constraction of Mathieu’s functions
    Computer Research and Modeling, 2012, v. 4, no. 1, pp. 31-43

    The modified two-sweep iteration procedure was proposed, built according to the least-squares method scheme, which determines progressive approximations to the periodic solution of Mathieu’s equation and his own function, considerably superior according to the accuracy earlier well-known results.

    Keywords: Mathieu’s equation, leastsquares method, twosweep iteration technique.
