Abstract

In this paper, we study the convergence of non-orthogonal wavelet expansions associated with dilation matrix in the Lp(ℝd) norm, 1 ≤ p < ∞ Moreover, the results of Zayed [1] have been extended using the approximate identity but the present method and approach are different from those adopted by Zayed [1].
