Application of the method of averaging to the problems of optimal control for ordinary differential equations on the semiaxis

Kichmarenko O. D.

↓ Abstract

Ukr. Mat. Zh. - 2018. - 70, № 5. - pp. 642-654

The method of averaging is applied to the nonlinear and linear (with respect to control) problems of optimal control on the semiaxis with small parameter and rapidly oscillating coefficients. It is shown that the solutions of the exact problem converge to the solutions of the averaged problem.

On Darboux vector in Lorentzian 5-space

Iyigün E.

↓ Abstract

Ukr. Mat. Zh. - 2018. - 70, № 5. - pp. 635-641

We introduce the Darboux vector in the Lorentzian 5-space. We give some characterizations of this vector in the space. In addition, we consider some special cases in the space.

On the approximation of the classes $W_{β}^rH^{α}$ by biharmonic Poisson integrals

Hrabova U. Z., Kalchuk I. V., Stepanyuk T. A.

↓ Abstract

Ukr. Mat. Zh. - 2018. - 70, № 5. - pp. 625-634

We obtain asymptotic equalities for the least upper bounds of the deviations of biharmonic Poisson integrals from functions of the classes $W_{β}^rH^{α}$ in the case where $r > 2, 0 \leq \alpha < 1$.
