On the Carleson measure characterization of BMOA functions on the unit ball

open access: yes, 1992
An equivalent form of the well-known Carleson measure condition that characterizes BMOA functions on the unit ball is given. As an application, it is proved that the Toeplitz operator T

The characteristics of BMOA on Riemann surfaces [PDF]

open access: yesKodai Mathematical Journal, 1992
The author gives a John-Nirenberg type theorem for BMOA on open Riemann surfaces. Some equivalent descriptions of BMOA on Riemann surfaces were given. For compact bordered Riemann surfaces similar results were given in an earlier joint work [\textit{He Yuzan} and \textit{Zhao Ruhan}, Chin. Sci. Bull. 36, No. 20, 1677-1682 (1991; Zbl 0764.30036)].

Multipliers of \(H^ p\) and BMOA

open access: yes, 1990
For functions \(f(z)=\sum^{\infty}_{0}a_ nz^ n\), \(g(z)=\sum^{\infty}_{0}b_ nz^ n\) analytic in the unit disk \({\mathbb{D}}\) write \(f*g(z)=\sum^{\infty}_{0}a_ nb_ nz^ n\) and \(M_ p(r,f)=(1/2\pi)\int^{2\pi}_{0}| f(re^{i\theta})^ p d\theta)^{1/p}\). The space \(H^ p\) is the set of analytic f with \(M_ p(r,f)=O(1)\) as \(r\to 1\).
