题目: Weighted BMO and Hankel operators between Bergman spaces 

报告人：赵如汉 （纽约州立大学）

摘要：We introduce a family of weighted BMO spaces in the Bergman metric on the unit ball of $\mathbb C^n$ and use them to characterize complex functions $f$ such that the big Hankel operators $H_f$ and $H_{\bar f}$ are both bounded or compact from a weighted Bergman space into a weighted Lesbegue space with possibly different exponents and different weights. 

As a consequence, when the symbol function $f$ is holomorphic, we characterize bounded and compact Hankel operators $H_{\bar f}$ between weighted Bergman spaces. 

This is a joint work with Jordi Pau and Kehe Zhu.
