题目：The cyclicity of composite functions in the Hardy space over the infinite polydisc

摘要：The cyclic vector problem on the Hardy space over the infinite polydisc is the analytic function space version of Wintner and Beulring's periodic dilation completeness problem. In this talk, I will mainly concentrate on characterizing cyclic vectors in terms of composition operators. Also, dilation theory for doubly commuting sequence of C.0 contractions is involved.
