Sharp type inequalities of maximal operators of means with respect to Vilenkin systems with monotone coefficients
arXiv:2101.09196
Abstract
In this paper we prove and discuss some new type inequalities of maximal operators of means with respect to the Vilenkin systems with monotone coefficients. We also apply these inequalities to prove strong convergence theorems of such means. We also show that these results are the best possible in a special sense. As applications, both some well-known and new results are pointed out.
