本文研究了Bergman空间上具有无界符号的迹类Toeplitz算子的问题.利用构造的方法,获得了L2(Un,dA)中的函数φ,φ在Tn中每一点的任何邻域内都是无界的,并且使得Tφ是Bergman空间La2(Un,dA)上的迹类算子的结果.
In this article, we study Toeplitz operators of trace class with unbounded symbols on Bergmen space La2(Un,dA) on the polydisk of several complex variables. By constructing the function φ in L2(Un,dA) which is unbounded on any neighborhood of each boundary point of Tn, we obtain Toeplitz operator Tφ is a trace class operator.
