On absolute generalized Hausdorff summability of orthogonal series
Abstract
In this paper we prove two theorems on absolute generalized
Hausdor summability of orthogonal series. These theorems give some
sucient conditions in terms of coecients of an orthogonal series under
which it is absolute generalized Hausdor summable. In addition, it is
veri ed that several known results are corollaries of the new results.
