Lower bounds for summability matrices on weighted sequence spaces

(Lobachevskii Journal of Mathematics, Volume XXVII)

The purpose of this paper is finding a lower bound for summability matrix operators on sequence spaces lp(w) and Lorentz sequence spaces d(w,p) and also the sequence space e(w,∞). Also, this study is an extension of some works of Bennett.
