Bounds for the norm of lower triangular matrices on the Cesaro weighted sequence space

This paper is concerned with the problem of finding bounds for the norm of lower triangular matrix operators from l(p)(w) into c(p)(w), where c(p)(w) is the Cesaro weighted sequence space and (w(n)) is a non-negative sequence. Also this problem is considered for lower triangular matrix operators from c(p)(w) into l(p)(w), and the norms of certain matrix operators such as Cesaro, Norlund and weighted mean are computed.
