↓ Abstract

Ukr. Mat. Zh. - 2019. - 71, № 2. - pp. 168-179

On the basis of V. Dzyadyk’s approximation method, we consider the problems of construction and theoretical substantiation of high-precision numerical-analytic algorithms for the piecewise polynomial approximation of the solutions of problems with pulsed action.
