摘要

We study series in terms of multiplicative Price systems with coefficients in the class of sequences of bounded variation. Necessary and sufficient conditions are obtained for estimating the norm of sums of such series in weighted Lebesgue spaces. The obtained conditions are formulated in terms of the weight function and the weight sequence.
