Аннотация
We give a characterization of elements of a subspace of a complex Banach space with the property that the norm of a bounded linear functional on the subspace is attained at those elements. In particular, we discuss properties of polynomials that are extremal in sharp pointwise Nikol’skii inequalities for algebraic polynomials in a weighted Lq-space on a finite or infinite interval.
