Introduction Let D be the open unit disk in the complex space dA the Lebesegue measure on D normalized so that A D 1. Let H D be the space of all analytic functions on D. Let a -1 p 0. f is said to belong to the weighted Bergman space denoted by A AS D if f e H D and II f II p a 1 ị f z p 1 - z 2 adA ra. When 0 p 1 it is complete metric space when p 1 it is a Banach space. Let z weight be a positive continuous function on D and n e N0. The nth weighted space on the unit disk denoted by a n D consists of all f e H D such that b. n f sup z f n z . zeD For n 0 the space becomes the weighted-type space H D for n 1 the Bloch-type space ổm D and for n 2 the Zygmud-type Z D . For more details about these spaces we recommend the readers to 1 2 . The expression bmỊn D f defines a semi-norm on the nth weighted space n D while the natural norm is given by n 1 II f II Ln D f j 0 b n D f . j 0 2011 Zhang and Zeng licensee Springer.
