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 \(\mathrm{BMOA}\).
