Abstract:
The Bernstein inequalities for trigonometric polynomials are generalized. For the sums of Fourier coefficients, upper bounds with certain constants are obtained with respect to values that characterize the structural properties of functions.
Key words and phrases:
trigonometric polynomials, Bernstein's inequality for derivatives, exact constants, moduli of continuity, Fourier coefficients.
