A sharp Hörmander estimate for multi-parameter and multi-linear Fourier multiplier operators
Jiao Chen, Danqing He, Guozhen Lu +2
In this paper, we investigate the Hörmander type theorems for the multi-linear and multi-parameter Fourier multipliers. When the multipliers are characterized by -based Sobole…

Bi-parameter trilinear Fourier multipliers and pseudo-differential operators with flag symbols
Guozhen Lu, Jill Pipher, Lu Zhang
The main purpose of this paper is to study Hölder type estimates for a bi-parameter trilinear Fourier multiplier with flag singularity, and the analogous pseudo-differential…
