| 摘 要： | 对以有界调和函数为符号的Ｔｏｅｐｌｉｔｚ算子给出了存在不变子空间的一个充分条件。对一类符号的Ｔｏｅｐｌｉｔｚ算子组的本质给出一个估计，刻画了有界区域上余解析Ｔｏｅｐｌｉｔｚ算子的点谱。

| Abstract: | In this paper,a sufficent candition is given for Toeplitz operaters with harmonic symbols to exist invariant Subspaces. For Fredholm Spectra of muti-Toeplitz operators with special Symbols,a Super-bound is found.Point spectra of Toeplitz operators with co-analytic Symbols are described. |
