摘要：

<正> In this paper, we continue studying the so-called non-linear best m-term one-sided approximationproblems and obtain the asymptotic estimations of non-linear best m-term one-sidedtrigonometric approximation under the norm Lp （1≤p≤∞） of multiplier function classes and thecorresponding m-term Greedy-liked one-sided trigonometric approximation results.
