,Maximization of Integral Functionals in ,,[,,, ,,], - ∞ ≤ ,, < ,, ≤ +∞,We describe extremal functions and rearrangements of the problem.where .. < 0 < .., and the kernel ψ has a finite number or a countable mono-tonely ordered set of points of sign changes on [.., ..], - ∞ ≤ .. < .. ≤ +∞. In particular, we give the solution of the problem (**) in the case of the entire line [.., ..] = ?.

,Sharp Kolmogorov Inequalities in ,,,,(?),Let ., .: 0 < m ≤ ., be integers. In this chapter we first describe the discrete family of Chebyshev ω-splines extremal in the problem .for certain choices of . and all concave modulii of continuity ω. Then, we characterize the extremal functions in the problem .for all . > 0 and α ∈ (0,1].
