Parameterization method for optimal control problems, which is contained in a finite parameterization of a seeking control function and calculation of first and second derivatives on the parameters of the problem"s functionals by using of conjugate variables, is created. The normal spline-collocation method for solution of integral and differential equations, particularly degenerated ones, is created. Regularization methods for nonlinear equations, inequalities and extremum problems, which are based on an explicit parameterization of input data and on using of multi-valued mappings, are created. The most effective method of extended minimization could be assumed as an expansion on nonlinear problems the last Tikhonov's regularization concept (1980–1985), according to which for obtaining a stable approximation of a solution of an ill-posed problem one have to find an element of minimal completeness in the join of solution set of the family of problems which are equivalent to the initial one with respect to input data accuracy. For inverse problem of the consumer demand theory solution methods in the class of differentiable utility functions are created. Numerical Analysis, Mathematical Economics
Biography
Graduated from Moscow Physical-Technical Institute in 1969 on specialty "Systems of automation control". In 1970–1976 worked for the Tashkent State University. In 1974 Ph.D. thesis "Optimization problems of processes with controllable discontinuities of phase trajectories" was defended in the MPhTI. During 1976–1990 worked for the Mathematics Institute of the Academy of Sciences of Kirghiz SSR. In this period I continued investigations on optimal control problems and turned to problems of numeric mathematics and modeling of demographic processes of a population that is heterogeneous on reproduction behavior. Since 1990 I work for the Ulyanovsk State University. My D.Sci. thesis "Extremum problems for measurements data processing" was defended in Computing Center of the Siberian Branch of the USSR ASc. in 1987. My education topics: Optimization methods, Ill-posed problems, Mathematical economics.
Member of the Academy of Nonlinear Sciences (President ac. V. M. Matrosov), Chief of the Ulyanovsk Branch of the Middle Volga Mathematical Society. I was awarded the sign "Honourable Employee of the Higher Education of Russia Federation".

\paper The parametrization method for optimal control problems
\paperinfo A method of numerical solution of optimal control problems is proposed, which consists in a finite parameterization of the required optimal control. The calculation of derivatives (the first and second order) of the problem functional and of constrains with respect to control parameters is fulfilled with the use of conjugated systems (first and second order).

\paper The method of normal spline-collocation
\paperinfo A method of numerical solution of integro-differential equations (including initial and boundary value problems of ODEs and integral equations of the first kind) is proposed. The method consists in transfer from the equation to a collocation system with arbitrary nodes, and a statement of the problem of minimizing some Sobolev-Hilbert norm of solutions of the collocation system. The arisen point and integral (for the integral component of the equation) functionals are transformed to canonical form, that is to the scalar product. The method is applicable (converges) for equations with arbitrary degenerate principal part.
