设F和G是函数组成的矩阵,它们的元素都是单位球上平方可积的解析函数,该文研究单位球向量值Bergman空间上的Toeplitz算子乘积TFTG,分别获得了算子TFTG*有界的充分条件和必要条件.
In this paper the authors obtain a sufficient condition and a necessary condition for the Toeplitz product TFTG. on vector-valued Bergman spaces of the unit ball to be bounded respectively, where F and G are matrices which entries are square-integrable and analytic functions on the unit ball.
