Exact Values of Widths of Some Functional Classes in L2 and Minimization of the Constants in Inequalities of Jackson – Stechkin Type
<p>In this paper, it is considered the extremal problem of finding the exact constants in inequalities of Jackson – Stechkin type between the best approximations of periodic differentiable functions f ∈ L (r) 2 [0, 2π] by trigonometric polynomials, and the average values with a positive weight...
