Abstract: | Let , where the and satisfy the following relations: and . Denote by B the class of all entire functions of exponential type bounded on the real axis. Under certain assumptions on the rate of approximation on E of a bounded function f by functions in B ( varies), we get some information about the smoothness of f. Bibliography: 4 titles. |
