经典算子的定量加权混合弱型不等式

Quantitative weighted mixed weak-type inequalities for classical operators

Sheldy Ombrosi, Carlos Perez, Jorgelina Recchi

摘要:

改进了Hardy-Littlewood极大函数和Calderón-Zygmund算子的几个混合弱型不等式.这些类型的不平等被认为是Muckenhoupt和惠登和后来的索耶估计$L^{1, \infty}(uv)$规范的$v^{-1}T(fv)$的特殊情况。重点是证明新的和更精确的定量估计涉及$A_p$或$A_\infty$常数的权重。

英文摘要:

We improve on several mixed weak type inequalities both for the Hardy-Littlewood maximal function and for Calderón-Zygmund operators. These type of inequalities were considered by Muckenhoupt and Wheeden and later on by Sawyer estimating the $L^{1, \infty}(uv)$ norm of $v^{-1}T(fv)$ for special cases. The emphasis is made in proving new and more precise quantitative estimates involving the $A_p$ or $A_\infty$ constants of the weights involved.
