研究了与非光滑核的奇异积分算子和加权Lipschitz函数相关的的Toeplitz算子Tb的sharp极大函数的点态估计,并应用该估计证明了Toeplitz算子Tb是从Lp(ω)到Lq(ω1-q)上的有界算子.此外还建立了与非光滑核的奇异积分算子和加权BMO函数相关的的Toeplitz算子Tb的sharp极大函数的点态估计,证明了这类Toeplitz算子是从Lp(μ)到Lq(v)上的有界算子.
This paper is concerned with point, wise estimates for the sharp maximal function of the Toeplitz operators T8 related to singular integral operators with non-smooth kernel and a weighted Lipschitz function. We show that Toeplitz operator Tb is bounded from Lp(w) to Lp(wl-q). On the other hand, we also establish pointwise estimates for the sharp maximal function of the Toeplitz operator related to singular integral operators with non-smooth kernel and a weighted BMO function and show that this Toeplitz operator Tb is bounded from LP(μ) to LP (v).
