报告摘要:In this talk, we study the characterizing problems of the similarity and reducing subspaces for the multiplication operator
on the weighted Sobolev algebra of the d-dimensional polydisc. It is shown that
is similar to 
and
has exactly
complete reducing subspaces. This result greatly promotes the corresponding results in the analytic function spaces.
