Dimeters in $L_2$ classes of differentiated functions determined by continuity moduli of higher orders

Sharp inequalities are obtained in the space $L_2$, connecting the best approximations of differentiable $2\pi$-periodic functions by trigonometric polynomials with integrals containing the higher-order moduli of continuity of the derivatives of these functions. The Kolmogorov widths of certain clas...
