摘要
该文研究了单位多圆柱情形Dirichlet型空间上的加权复合算子的谱.对一类紧加权复合算子,给出了其谱的完全刻画,推广了已有结果.
In this paper, the authors study the spectra of weighted composition operators on Dirichlet type spacesDa(Un) defined on the unit polydisc Un in Cn. Some spectral characterizations of a class of compact weighted composition operators on Dα(Un) are obtained, which extend some previous results.
