报告摘要： The pseudo-differential operators have played important roles in Harmonic Analysis and PDE. The study of linear pseudo-differential operators can be traced back to the famous work of H\"{o}rmander. The bilinear pseudo-differential operators was orginated in the works of Coifman and Meyer. Since then, many works have been done,and big differences been shown about the linear and bilinear pseudo-differential operators. In this talk, I will introduce some recent work on the boundedness of multilinear pseudo-differential operators.Including the local decay estimates,the weighted mixed weak type inequalities and the sharp weighted strong estimates.
