对双圆盘的Bergman空间上k阶斜Toeplitz算子的交换性展开了研究,得到了以共轭解析函数为符号的k阶斜Toeplitz算子可交换的充要条件是其符号函数线性相关.

英文摘要：

In this paper, the commutativity of k -order slant Toeplitz operator on the Bergman space of bidisk are discussed. The necessary and sufficient condition is obtained. For the commutativity of k-order slant To- eplitz operators with co-analytic symbols ,their symbol function are linearly dependent.
