| Sumario: | This paper is devoted to the weak and strong estimates for the linear and multilinear fractional Hausdorff operators on the Heisenberg group Hn{{\mathbb{H}}}^{n}. A sharp strong estimate for TΦm{T}_{\Phi }^{m} is obtained. As an application, we derive the sharp constant for the product Hardy operator on Hn{{\mathbb{H}}}^{n}. Some weak-type (p,q)\left(p,q)
(1≤p≤∞)\left(1\le p\le \infty ) estimates for TΦ,β{T}_{\Phi ,\beta } are also obtained. As applications, we calculate some sharp weak constants for the fractional Hausdorff operator on the Heisenberg group. Besides, we give an explicit weak estimate for TΦ,β→m{T}_{\Phi ,\overrightarrow{\beta }}^{m} under some mild assumptions on Φ\Phi . We extend the results of Guo et al. [Hausdorff operators on the Heisenberg group, Acta Math. Sin. (Engl. Ser.) 31 (2015), no. 11, 1703–1714] to the fractional setting. |
