 A double integral characterization of a Bergman type space and its M\"obius invariant subspace Bull. Korean Math. Soc. 2019 Vol. 56, No. 6, 1643-1653 https://doi.org/10.4134/BKMS.b190053Published online August 6, 2019Printed November 30, 2019 Cheng Yuan, Hong-Gang Zeng Guangdong University of Technology; Tianjin University Abstract : This paper shows that if $1-1-\frac{p}{2}$ and $f$ is holomorphic on the unit ball $\bbn$, then $$\ibn |Rf(z)|^p(1-|z|^2)^{p+\alpha} \rd v_\alpha(z)<\infty$$ if and only if $$\ibn\ibn\frac{|f(z)-f(w)|^p}{|1-\langle z,w\rangle|^{n+1+s+t-\alpha}} (1-|w|^2)^s(1-|z|^2)^t \rd v(z)\rd v(w)<\infty,$$ where $s,t>-1$ with $\min(s,t)>\alpha$.
