为了/e?“(R2),令(7 ε/)"(ε)=(1 -|£| 2 〜 2)i/(E)。Carleson和Sjolin的一个著名定理是:当a > 0时,T”定义Z,4上的有界算子。本文得到了一个显式的加权不等式:/ sup \T%f(x)\2w(x)dx ti(\f\2Paw(x)dx,0 0.这加强了Carleson和Sjolin的上述定理。该方法给出了与R2的一般适当光滑的径向傅立叶乘法器相关的最大算子的信息。
For/e ?"(R2), let (7£/)"(£) = (1 - |£|2«2)i/(£). It is a well-known theorem of Carleson and Sjolin that T" defines a bounded operator on Z,4 if a > 0. In this paper we obtain an explicit weighted inequality of the form / sup \T%f(x)\2w(x)dxti( \f\2Paw(x)dx, 0 0. This strengthens the above theorem of Carleson and Sjolin. The method gives information on the maximal operator associated to general suitably smooth radial Fourier multipliers of R2.
