The Hörmander multiplier theorem, II: The bilinear local $L^2$ case

Loukas Grafakos, Danqing He, Petr Honzík

摘要:

我们利用张量积型小波得到了$\mathbb R^n\times \mathbb R^n$上双线性乘子算子与$\mathbb R^{2n}$上Hörmander乘子算子的有界性.我们专注于本地$L^2$的情况下,我们得到的最小光滑假设下的$n/2$衍生物的有界性。我们还提供了反例,以获得所有的指数集的必要条件。

英文摘要:

We use wavelets of tensor product type to obtain the boundedness of bilinear multiplier operators on $\mathbb R^n\times \mathbb R^n$ associated with Hörmander multipliers on $\mathbb R^{2n}$ with minimal smoothness. We focus on the local $L^2$ case and we obtain boundedness under the minimal smoothness assumption of $n/2$ derivatives. We also provide counterexamples to obtain necessary conditions for all sets of indices.
