Theory of interpolation in problem form. Part 2. With a foreword by F. D. Gahov. (Теория интерполирования в задачах. Часть 2.) (Russian) Zbl 1236.41006
Minsk: Izdat. “Vyšèĭšaja Škola”. 256 p. (1977).
Summary: The author presents some results of interpolation theory in the problem-hint-solution format. A number of the results are interesting but the book also contains a certain amount of insignificant material.
Table of Contents: 1. Interpolation formulas for trigonometric polynomials of half-integer degree; 2. Convergence of certain interpolation processes for discontinuous functions; 3. Degree of approximation of given function classes by interpolation polynomials; 4. Inequalities for polynomials satisfying interpolatory conditions; 5. Inequalities for polynomials satisfying certain conditions on a large set of points; 6. Extremal properties of rational functions.
For Part 1 see Zbl 1236.41005.
