(ii)若权函数对(u,v)满足对某个r>1及对任意方体Q,(?) 则位势型算子T_Φ满足下列双权弱(p,q)型不等式:(?)其中1For a non-negative,locally integrable functionΦ on R~n,the potential typeoperators associated toΦis defined by We assume that the kernelΦsatisfies the following weak growth condition:thereexist constantsδ,c,0≤ε<1 with the property that for all k∈Z,and (?)(t)/t~n→0,as t→∞.where The main results are the following: (i)Letδ>0,for any weightω,we have (ii)Given 11 and any cube Q,then the potential type operators T_Φsatisfies the following two-weight weak type(p,q)inequality,
