摘要：

       In 1970s Coifman and Meyer proved the famous Coifman-Meyer theorem, which generalized Mihnlin's multiplier theorem to the multilinear setting. The study of   multilinear H\"ormander multipliers, a natural generalization of Coifman-Meyer multipliers, became an important topic in multilinear harmonic analysis in recent years. In this talk, we will survey the development of multilinear H\"ormander multipliers, and discuss a sharp multiparameter generalization. More precisely, we will present a result concerning the boundedness of multilinear multiparameter H\"ormander multipliers, and give counterexamples indicating its sharpness. This is joint work with Chen, Lu, Park, and Zhang.
