Bellman函数与仿积的$L^p$估计

Bellman functions and $L^p$ estimates for paraproducts

Vjekoslav Kovač, Kristina Ana Škreb

摘要:

本文给出了一个与并元仿积的$L^p$有界性相关的Bellman函数的显式公式,并将其看作是双线性算子或三线性形式.然后,我们应用相同的贝尔曼函数在各种其他设置,给几个经典运营商的估计自包含的替代证明。这包括Bañuelos和Bennett的鞅仿积以及关于热流的仿积。

英文摘要:

We give an explicit formula for one possible Bellman function associated with the $L^p$ boundedness of dyadic paraproducts regarded as bilinear operators or trilinear forms. Then we apply the same Bellman function in various other settings, to give self-contained alternative proofs of the estimates for several classical operators. These include the martingale paraproducts of Bañuelos and Bennett and the paraproducts with respect to the heat flows.
