On the growth rate of powers of a strongly Kreiss bounded operator on -spaces

arXiv:2302.14135

Abstract

Let be a strongly Kreiss bounded linear operator on . We obtain a bound on the rate of growth of the norms of the powers of . The bound is optimal with respect to the polynomial scale. The proof makes use of Fourier multipliers, in particular of the Littlewood-Paley inequalities on arbitrary intervals as initiated by Rubio de Francia and developed by Kislyakov and Parilov.
