Abstract
In this paper, we consider those multiplication operators M p on \({L_a^2(\mathbb{D}^2)}\) defined by a class of polynomials p. Also, this paper consider the reducing subspaces of M p , the von Neumann algebra \({ \mathcal{W}^*(p)}\) generated by M p , and its commutant \({\mathcal{V}^*(p) = \mathcal{W}^*(p)'.}\) The structure of \({\mathcal{V}^*(p)}\) is completely determined, along with those reducing subspaces of M p .
