先得到Toeplitz型算子的加权不等式,然后利用外推方法得到了当Hardy-Littlwood极大算子在变指数Lebesgue空间有界时,Toeplitz型算子在变指数Lebesgue空间的有界性和向量值估计.
Firstly,a weighted norm inequality of Toeplitz type operaters is obtained.Then by applying the extrapolation method the boundedness and a vector estimate of Toeplitz type operators on variable exponent Lebesgue spaces are obtained,on which the Hardy-Littlewood maximal operator is bounded.
