Sharp Bounds for Fractional One-sided Operators

引用

Acta Mathematica Sinica,English Series 2016年第11期32卷 1255-1278页

作者： Maria Silvina RIVEROS Raul emilio VIDAL FaMAF-CIEM UNC-CONICET Ciudad Universitaria 5000 Cdrdoba Argentina

In this paper, we characterize the sharp boundedness of the one-sided fractional maximal function for one-weight and two-weight inequalities. Also a new two-weight testing condition for the one-sided fractional maximal function is introduced extending the work of Martin-Reyes and de la Torre. Improving some extrapolation result for the one-sided case, we get weak sharp bounded estimates for one-sided fractional maximal function and weak and strong sharp bounded estimates for one-sided fractional integral.
