Abstract

This paper is concerned with the problem of finding theupper and lower bounds of matrix operators from weighted sequence spaceslp(v,I) into lp(v,F). We consider certain matrix operators such asCesàro, Copson and Hilbert which were recently considered on the usual weighted sequence spaces lp(v).
