Let D be the open unit disk in the complex plane and H (D) denote the space of all holomorphic functions in D. For α>− 1, we define the weighted measure dAα on D by dAα (w)=[log (1/| w|)] α dA (w), where dA is the normalized Lebesgue measure on D. For 0< p<∞ and α>− 1, the weighted Bergman space A p α (D) is defined to be those functions f∈ H (D) satisfying fAp α
