在调和Bergman空间上，给出了径向函数符号的Toeplitz和小 Hankel算子乘积为小 Hankel 算子的充要条件，完全刻画了拟齐次符号小 Hankel算子和Toeplitz算子有关乘积或交换子为有限秩的条件。%In this paper,we first give the necessary and sufficient condition for the product of a To-eplitz operator and a small Hankel operator with radial symbols to be a small Hankel operator.Next,we completely characterize the condition for finite rank product or commutator of small Hankel and Toeplitz operators with quasi homogeneous symbols.
