In [6], Remark (d), Lubinsky mentions the possibility of a slightly modified Jackson-Favard inequality in the form E n (f, w) ≤ η n ‖ w f ′ ‖ + ‖ w f ‖ { x ≥ ξ n} where {η n} ↘ 0 and {ξ n} ↗ ∞ are two sequences independent of f. In fact, such an estimate can be given for higher ...

WebFeb 15, 2024 · The Bohr-Favard inequality was studied also in [4, 7, 9]. The main purpose of this paper is to derive a new Bohr-Nikol’skii inequality for weighted Lebesgue spaces, which combines the inequality of Bohr-Favard and the Nikol’skii idea of inequality for functions in different metrics (see [12, 13]). WebIn this paper, we obtain extensions of majorization type results and extensions of weighted Favard's and Berwald's inequality. We prove positive semi-definiteness of matrices generated by differences deduced from majorization type results and differences deduced from weighted Favard's and Berwald's inequality. This implies a surprising ...
