摘要
本文给出了 Dirichlet空间上 Toelpitz算子为紧算子的充要条件,并证明具有 C1-符号的 Toeplitz算子为紧算子当且仅当它为零算子,当且仅当符号的边值为零.
In the present paper, an iff condition on the compactness of Toeplitz operators on Dirichlet spaces is obtained, in addition, it is proved that a Toeplitz operator with C1- symbol is compact if and only if it equals zero if and only if the boundary value of its symbol equals zero.
