Abstract: | Let φ 1 and φ 2 be holomorphic self-maps of the unit polydisk \(\mathbb{D}^N\), and let u 1 and u 2 be holomorphic functions on \(\mathbb{D}^N\). We characterize the boundedness and compactness of the difference of weighted composition operators W φ1, u1 and W φ2, u2 from the weighted Bergman space \(A_{\vec \alpha }^p\), 0 < p < ∞, \(\vec \alpha = \left( {\alpha _1 , \ldots ,\alpha _{\rm N} } \right)\), α j > ?1, j = 1,..., N, to the weighted-type space H υ ∞ of holomorphic functions on the unit polydisk \(\mathbb{D}^N\) in terms of inducing symbols φ 1, φ 2, u 1, and u 2. |
