摘要

In this paper, by applying the properties of the kernel function of sub-Laplace operators, we study the fractional Leibniz rules for bilinear and biparameter spectral multipliers on the product space of Carnot groups. Then we take a system of PDEs as an example to show its application in proving the scattering problem of differential equations.
