摘要
We introduce a kernel function induced by a continuous function f on the unit circle, and show that the corresponding integral operator on the standard Bergman space is a bounded, compact or Hilbert-Schmidt operator precisely when f belongs to the big Zygmund class Lambda(*), the little Zygmund class lambda(*) or the Sobolev class H-3/2, respectively. This may be considered as the infinitesimal version of the main result obtained in Hu and Shen (2012) [9] by two of the authors.
