摘要
In this paper we improve and complement a result by M oricz and Siddiqi [12]. In particular, we prove that their inequality of the N orlund means with respect to the Walsh system holds also without their additional condition. Moreover, we prove some new approximation results and inequalities in Lebesgue spaces for any 1 <= p < infinity
