题目：On bilinear Hörmander multipliers

摘要: The study of multilinear multipliers goes back to the work of Coifman and Meyer in 1970s, who extended Mihlin's result to the bilinear setting. Their result is known as the Coifman-Meyer theorem, which turned to be useful in harmonic analysis and PDE. As a natural generalization of Coifman-Meyer multipliers, the multilinear Hörmander multiplier becomes an important topic in multilinear harmonic analysis.

In this talk, we will survey the development of multilinear Hörmander multipliers, and discuss a bi-parameter generalization. This is joint work with Chen, Lu, Park, and Zhang.
