On the Littlewood--Paley--Rubio de Francia inequality for the bounded Vilenkin systems
arXiv:2106.00071
Abstract
The one-sided Littlewood--Paley inequality for arbitrary intervals was proved by Rubio de Francia. Later, N. Osipov proved its analogue for the system of Walsh functions. In this paper, this inequality is proved for more general Vilenkin systems.
