摘要：
This paper characterizes the compactness of a linear combination of three composition operators on A(alpha)(p)(B-N), the weighted Bergman space over the unit ball B-N in C-N. In this setting, we show that there is no cancellation property for the compactness of double difference of composition operators, which extends Koo-Wang's results over the unit disk in [13]. In addition, we investigate the compactness and essential norm estimate of the differences of weighted composition operators between weighted Bergman spaces.
