Abstract

In this paper we have introduced a new sequence ideal using Orlicz function and the
notion of de la Valle´e Poussin mean. It is proved that the Cesa´ ro-Orlicz sequence ideal is complete
under a suitable norm. Moreover, it is shown that Cesa´ ro-Orlicz sequence ideal is maximal, and if
the Orlicz function satisfies D2-condition at zero then it is also minimal.
