本文刻画了当1 <p <∞,α >−1时加权Bergman空间上的紧算子.主要结果表明:算子是紧的当且仅当它属于Toeplitz代数且其Berezin变换在球的边界上为零.
In this paper we characterize the compact operators on the weighted Bergman spaceswhen 1 <p <∞ andα >−1. The main result shows that an operator onis compact if and only if it belongs to the Toeplitz algebra and its Berezin transform vanishes on the boundary of the ball.
