Abstract

We investigate the efficiency of the Thresholding Greedy Algorithm, by comparing it to optimal “weighted” approximations. For a weight w, we describe w-greedy, w-almost-greedy, and w-partially-greedy bases, and examine some properties of w-semi-greedy bases. To achieve these goals, we introduce and study the w-Property (A).
