1. Compactness of Product Operators on the Bergman Space. Author Mao Fa Wang and Pei de Liu Subjects *LINEAR operators, *MATHEMATICAL physics, *MATHEMATICAL functions, *DIFFERENTIAL equations, *SET theory, *MATHEMATICS Abstract In this paper, we study the compactness of the product of a composition operator with another one’s adjoint on the Bergman space. Some necessary and sufficient conditions for such operators to be compact are given. [ABSTRACT FROM AUTHOR] Published 2005 Full Text View/download PDF
