本文刻画了单位多圆盘上Bergman-Sobolev空间上Toeplitz算子和Toeplitz乘积的紧性和Fredholmness性。我们还计算了这些空间上有限Toeplitz乘积的有限和的本质范数。
In this paper, we characterize the compactness and Fredholmness of Toeplitz operators and Toeplitz products on Bergman-Sobolev spaces over the unit polydisk. We also calculate the essential norm of finite sums of finite Toeplitz products on these spaces.
