چکیده
|
This paper is concerned with the problem of finding a lower bound for certain matrix operators such as hausdorff and hilbert matrices on sequence spaces lp(w) and lorentz sequence spaces d(w,p), which is recently considered in [7,8], similar to [13] considered by j. pecaric, i. peric and r. roki. also, this study is an extension of some works which are studied before in [1,2,7,8].
