Доказана теорема о выполнении интерполяционных условий. Найден класс многочленов, для которых интерполяционная формула точна. Построена оценка погрешности полученной формулы. Рассмотрены частные случаи ин- терполяционных формул для систем тригонометрических и экспоненциальных функций. </p></abstract><trans-abstract xml:lang="en"><p>The generalized interpolation formula of Hermite – Birkhoff type with respect to the arbitrary Chebyshev system of functions is constructed. Theorem on the satisfaction of the interpolation conditions is proved. A class of polynomials, for which the interpolation formula is exact, is determined. The error estimate of the obtained formula is constructed. The particular cases of the interpolation formula for the systems of trigonometric and exponential functions are considered.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Худяков А.
