The class of bounded mean oscillation functions, known as the John-Nirenberg space (BMO), plays crucial role in harmonic analysis and complex analysis. In this talk, we present two kinds of generalization of the BMO. The first is known as Campanato spaces, and the second is the so called general family of function spaces F(p, q, s), or the Zhao’s space. We present the Littlewood-Paley characterization of Campanato spaces and construct the relations between this space and F(p, q, s). We also investigate the boundary value, Corona theorem, and interpolating sequences for a Moebius invariant general family of function spaces. Moreover, we introduce an integral operator preserving the Carleson measures and characterize the distance from the F(p, q, s) spaces to the Bloch-type spaces.
