摘要
Doubly commuting invariant subspaces of the Bergman space and the Dirichlet space over the unit polydisc (with ) are investigated. We show that for any non-empty subset of and doubly commuting invariant subspace of the Bergman space or the Dirichlet space over , restriction of the multiplication operator tuple on , always possesses generating wandering subspace of the form boolean AND(k)(i=1) (S circle minus Z(alpha i) S).
