ON THE LEAST DEVIATIONS OF THE FUNCTION $ \operatorname{sign} x$ AND ITS PRIMITIVES FROM THE RATIONAL FUNCTIONS IN THE $ L_p$ METRICS, $ 0 < p \leqslant \infty$

Abstract

In this paper estimates of weak equivalence type, as , are given for the least deviations of the functions in the metric of from the rational functions of degree . Specifically it is shown that ( if ); in particular, Bibliography: 9 titles.
