A refinement of Kolmogorov's inequality

Abstract

AbstractFor any n-times differentiable function f with uniform bounds on f and f(n), we study the pair of values (f(j)(t), f(j + 1)(t)) for an arbitrary real t and a prescribed j = 0,…, n − 1. A given value of f(j)(t) determines admissible values for f(j + 1)(t). These values are exactly determined in terms of the Euler spline En(t). Special differentiation formulas of cardinal interpolation type are developed to solve the problem
