鞅变换、并元移位和希尔伯特变换:矩阵加权空间有界的一个充分条件

Martingale transforms, the dyadic shift and the Hilbert transform: a sufficient condition for boundedness between matrix weighted spaces

Robert Kerr

摘要:

给出了鞅变换从$L^2(V)$到$L^2(U)$是一致有界的矩阵权$U$和$V$的充分条件.我们还表明,这些条件意味着一致有界的并矢位移以及这些空间之间的希尔伯特变换的有界性。

英文摘要:

We show sufficient conditions on matrix weights $U$ and $V$ for the martingale transforms to be uniformly bounded from $L^2(V)$ to $L^2(U)$. We also show that these conditions imply the uniform boundedness of the dyadic shifts as well as the boundedness of the Hilbert transform between these spaces.
