本文研究了中单位球上的多重调和Bergman空间上具有拟齐次或分离拟齐次符号的Toeplitz算子的一些代数性质。我们确定当产品的两个Toeplitz运营商与某些单独的准齐次符号是Toeplitz运营商。其次,我们讨论了一类Toeplitz算子的零积问题,其中一个算子的符号分别是拟齐次的,而另一个算子的符号是拟齐次函数,并证明了当其中一个算子的符号分别是拟齐次的,而另一个符号是任意的时,两个Toeplitz算子的零积问题只有平凡解.最后,我们还刻画了某些拟齐次或分离拟齐次Toeplitz算子的交换性。
We study some algebraic properties of Toeplitz operator with quasihomogeneous or separately quasihomogeneous symbol on the pluriharmonic Bergman space of the unit ball in . We determine when the product of two Toeplitz operators with certain separately quasi-homogeneous symbols is a Toeplitz operator. Next, we discuss the zero-product problem for several Toeplitz operators, one of whose symbols is separately quasihomogeneous and the others are quasi-homogeneous functions, and show that the zero-product problem for two Toeplitz operators has only a trivial solution if one of the symbols is separately quasihomogeneous and the other is arbitrary. Finally, we also characterize the commutativity of certain quasihomogeneous or separately quasihomogeneous Toeplitz operators.
