摘要： We introduce a new space IDA of locally integrable functions whose integral distance to holomorphic functions is fifinite. By using IDA and ∂-estimates, we characterize boundedness and compactness of Hankel operators on weighted Fock spaces in Cn. As an application, for bounded symbols, we show that the Hankel operator Hf is compact if and only if Hf¯ 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. Department of Mathematics, Huzhou University, Huzhou, Zhejiang 313000, China
