报告摘要:In 2006, Henry Helson introduced the multiplicative Hankel matrix which is a matrix whose entries a_{m,n} depend on the product of m and n. He observed that the multiplicative Hankel matrix can be realized as the (small) Hankel operator on the Hardy space of infinite-dimensional torus (for this reason, it is also called Helson operator). In this talk, we will introduce the background and progress on Helson operator. We will also introduce some open problems in this topic.
