| 1 | Endpoint estimates for n-dimensional Hardy operators and their commutators显示文摘In this paper,the sharp bound for the weak-type(1,1) inequality for the n-dimensional Hardy operator is obtained.Moreover,the precise norms of generalized Hardy operators on the type of Campanato spaces are worked out.As applications,the corresponding norms of the Riemann-Liouville integral operator and the n-dimensional Hardy operator are deduced.It is also proved that the n-dimensional Hardy operator maps from the Hardy space into the Lebesgue space.The endpoint estimate for the commutator generated by the Hardy operator and the(central) BMO function is also discussed. | ZHAO FaYou FU ZunWei LU ShanZhen | 2012 | Science China Mathematics2012，55，10： | 19 |
| 2 | Commutators of n-dimensional rough Hardy operators显示文摘In this paper, we study central BMO estimates for commutators of n-dimensional rough Hardy operators. Furthermore, λ-central BMO estimates for commutators on central Morrey spaces are discussed. | FU ZunWei LU ShanZhen ZHAO FaYou | 2011 | Science China Mathematics2011，54，1： | 7 |

| 4 | Some q-inequalities for Hausdorff operators显示文摘我们为形式 $$\int_0 ^的 Hausdorff 类型不平等的一些q分析变体计算锋利的界限{+ \infty }{{{ \left ({ \int_0 ^{+ \infty }{ \frac {{ \phi \left ( t \right )}}{ t } f\left ({ \frac { x }{ t }} \right ){ d_q } t }} \right )}^ p }{ d_q } x } \leqslant { C_\phi } \int_0 ^ b {{ f ^ p } \left ( t \right )}{ d_q }t$$。作为应用,我们获得古典积极不可分的操作员的几锋利的 q 分析不平等,包括强壮的操作员和它的伴随操作员, Hilbert 操作员,和 Hardy-Littlewood-Pter 准备吗?? | Jiuhua GUO Fayou ZHAO | 2017 | Frontiers of Mathematics in China2017，12，4： | 0 |
| 5 | Littlewood-Paley Functions and Triebel-Lizorkin Spaces,Besov Spaces显示文摘We establish Littlewood-Paley charaterizations of Triebel-Lizorkin spaces and Besov spaces in Euclidean spaces using several square functions defined via the spherical average,the ball average,the Bochner-Riesz means and some other well-known operators.We provide a simple proof so that we are able to extend and improve many results published in recent papers. | Dashan Fan Fayou Zhao | 2021 | Analysis in Theory and Applications2021，37，3： | 0 |
