内容摘要:

We introduce a new space IDA of locally integrable functions whose integral distance to holomorphic functions is finite. By using IDA and dbar-estimates, we characterize boundedness and compactness of Hankel operators on weighted Fock spaces in C^n.As an application, for bounded symbols, we show that the Hankel operator H_f is compact if and only if H_ {\bar f} is compact, which complements the classical compactness result of Berger and Coburn. We also apply our results to the Berezin-Toeplitz quantization and answer a related question of Bauer and Coburn.
