摘要
本文研究带权u的Sharp函数和极大函数M_uf之间的关系,首先建立它们(关于测度ωdx)的非增重排函数和之间的一个不等式,进而证明,只要ωdx,udx是可比较测度,当时,就有,其中常数C与f,p(1≤p<+∞)无关。
In this paper we study the relation between the weighted sharp function andthe weighted maximal function M_uf. First,we give an inequality for their nonincreasing,rear-rangement functions and with respect to measure wdx .Then.for the comparable measures wdx udx we prove that there exist aconstant C.which independs on f and p(1≤p≤+∞),such that .when
