Invariant subspaces and reducing subspaces of weighted Bergman space over bidisk

抄録

In this paper, we study the invariant subspace and reducing subspace of the weighted Bergman space over bidisk. The minimal reducing subspace of Toeplitz operator T_z^N = T_{z1^N z2^N} is completely described, and Beurling-type theorem of some invariant subspace of the weighted Bergman space over bidisk is also obtained.
