Abstract
It is well known that a harmonic function is in a Bergman space if and only if it satisfies some Hardy–Littlewood type integral estimates. In this paper, we extend this result to harmonic Bergman–Orlicz spaces. As an application, Lipschitz-type characterizes of harmonic Bergman–Orlicz spaces on the unit ball with respect to pseudo-hyperbolic, hyperbolic and Euclidean metrics are established. In addition, the boundedness of a map** defined by a difference quotient of harmonic function is discussed.
