多线性Fourier乘子在Hardy空间上的有界性

On the boundedness of multilinear Fourier multipliers on Hardy spaces

Jin Bong Lee, Bae Jun Park

摘要:

本文研究了Hardy空间上的多线性Fourier乘子算子。特别地,在适当的消去条件下,证明了Hörmander型多线性Fourier乘子算子从$H^{p_1} \times \cdots \times H^{p_m}$到$H^p$(对于$0<p_1,\dots,p_m\le 1$和$1/p_1 + \cdots 1/p_m = 1/p$)是有界的.因此,我们将作者的三线性估计(arXiv:2107.00225)扩展到一般的多线性估计,并改进了作者Lee,Heo,Hong,Park和Yang(Math.Ann.381:499-555,2021)在极限情况下的有界性结果。

英文摘要:

In this paper, we study multilinear Fourier multiplier operators on Hardy spaces. In particular, we prove that the multilinear Fourier multiplier operator of Hörmander type is bounded from $H^{p_1} \times \cdots \times H^{p_m}$ to $H^p$ for $0<p_1,\dots,p_m\le 1$ with $1/p_1 + \cdots 1/p_m = 1/p$, under suitable cancellation conditions. As a result, we extend the trilinear estimates of the authors(arXiv:2107.00225) to general multilinear ones and improve the boundedness result of the authors, Lee, Heo, Hong, Park, and Yang(Math. Ann. 381 : 499-555, 2021) in limiting situations.
