Fredholm and Schatten Class Operators on Bergman Spaces with Exponential Weights
In this paper, we give a characterization of Fredholmness of the Toeplitz operators on the Bergman spaces with exponential weights in when . Also, we obtain the sufficient and necessary conditions which the Toeplitz and Hankel operators on belong to -Schatten class, where is a continuous increasing convex function.
