UDC 517.5 We establish a new theorem on correlation between the sharp constants in the Kolmogorov type inequalities and the sharp constants in the Kolmogorov–Remez type inequalities for differentiable periodic functions. As a consequence, we obtain new sharp Kolmogorov–Remez type inequalities for s...
