A Littlewood-Paley Type Theorem for Bergman Type Spaces LI Teng-fei (Shanwei Vocational Technical College, Shanwei Guangdong 516600, China) We are familiar with the Littlewood-Paley -functions characterization of the Hardy space. In this paper, we prove that the original Littlewood-Paley g-functions can be used to characterize Bergman type spaces as well.
