摘要：

In this note, we obtain a Tauberian theorem for a class of regular lower triangular matrices operating on cosine series with coefficients tending to zero. As corollaries we obtain Tauberian theorems for weighted mean, Norlund, and Hausdorff matrices. (C) 2020 Mathematical Institute Slovak Academy of Sciences
