本文首先讨论了调和Bergman空间上具有拟齐次符号的Toeplitz算子(即符号形式为e ipθ φ,其中φ为径向函数)的一些基本结果。然后我们确定了两个具有拟齐次符号的Toeplitz算子的乘积何时为Toeplitz算子。
In this paper, we first discuss some basic results concerning Toeplitz operators with quasihomogeneous symbols (i.e., symbols being of the form e ipθ ϕ, where ϕ is a radial function) on the harmonic Bergman space. Then we determine when the product of two Toeplitz operators with quasihomogeneous symbols is a Toeplitz operator.
