## A note on the essential norm of weighted composition operators on BMOA.(English)Zbl 1345.30080

Summary: We give some new estimates for the essential norm of weighted composition operators on the space $$\mathrm{BMOA}$$. As a corollary, we obtain a new characterization for the compactness of weighted composition operators on the space $$\mathrm{BMOA}$$.
