本文研究了单位多圆盘加权Bergman空间AΦp(Dn)上的Toeplitz算子.利用多圆盘函数论,获得了L∞(Dn)的使得符号在其中的Toeplitz算子的半换位子是紧算子的最大自伴子代数Q,并计算了符号在Q中的Toeplitz算子的本质谱.
In this article,we study Toeplitz operators on the weighted Bergman space AΦp(Dn).By using polydisk function theory,we obtain the largest self-adjoint subalgebra Q of L∞(Dn) such that the semi-commutators of any two Toeplitz operators on the weighted Bergman space AΦp(Dn) with symbols in Q are compact,and calculate the essential spectrum of Toeplitz operator on AΦp(Dn) with the symbol in Q.
