Abstract: In this paper we extend previously obtained results on $L^p$norm inequalities $(1<p<\infty)$ for square functions, oscillation and variation operators, with $\mathbb Z$ actions, to the case of $\mathbb Z^d$actions. The technique involves the use of a result about vector valued maximal functions, due to Fefferman and Stein, to reduce the problem to a situation where we can apply our previous results.
