Abstract We consider the multiplication operator M z 1 n z 2 n on a certain closed subspace L a , α 2 + + ( A r 2 ) of weighted Bergman spaces L a , α 2 ( A r 2 ) over the biannulus A r 2 . We prove that the operator M z 1 n z 2 n is similar to ⨁ 1 n 2 M z 1 z 2 on L a , α 2 + + ( A r 2 ) . Moreover, the reducing subspaces of M z 1 n z 2 n are investigated.

二元环上伯格曼空间子空间上的算子 Mz1nz2n

摘要 我们考虑乘法算子M z 1 nz 2 n 在二元环A r 2 上的加权Bergman 空间L a , α 2 (A r 2 ) 的某个闭合子空间L a , α 2 + + (A r 2 ) 上。我们证明了算子M z 1 nz 2 n 类似于L a , α 2 + + (A r 2 ) 上的⨁ 1 n 2 M z 1 z 2 。此外,研究了M z 1 nz 2 n 的约简子空间。
