ON RATIONAL APPROXIMATIONS OF FUNCTIONS WITH A CONVEX DERIVATIVE

Mathematics of the USSR-Sbornik, 1974
Let be the least uniform deviation of a continuous function () from the rational functions of degree not greater than ().Theorem. Suppose a function is given on an interval and is times differentiable , its th derivative being convex. Then where is a constant depending on and .The estimate is sharp for any and any modulus of continuity of ...
