Let M be an invariant subspace of L2 (T2) on the bidisc. v1 and v2 denote the multiplication operators on M by coordinate functions z and w, respectively. In this paper we study the relation between M and the commutator of and V2. For example, M is studied when the commutator is self-adjoint or finite rank
