摘要：

In our recent work on characterization of completely bouded Fourier multipliers between endpoint-exponent Hardy spaces, we discover an unexpected connection of the completely bounded Fourier multipliers and an exact self-absorption property for Hankel operators associated with monoids. We establish such absorption property for a very large class of monoids including all group embeddable ones and all those with fisrt order lunar condition. We also show that any spatial compression of the regular representation of any countable group satisfy such absorption property, which should be compared to the famous Fell absorption principle for groups. The talk is based on joint work with Yong HAN and Zipeng WANG.
