Abstract:
We obtain estimates for Lp-norms of simple partial fractions in terms of their Lr-norms on limited and unlimited segments of the real axis for different p>1 and r>1 (S. M. Nikolskii type inequalities). We adduce examples and remarks about sharpness of these inequalities and sphere of their application.
Keywords:
simple partial fractions, Lp-norms, estimates for derivatives of simple partial fractions.
