摘要：
We show that a weighted composition operator W psi,phi is compact on BMOA precisely when it is unconditionally converging. As a direct con-sequence to this result we deduce that all weakly compact or completely con-tinuous weighted composition operators on BMOA are compact. The proof of this result is based on a new simplified function-theoretic characterization of the compactness of weighted composition operators on BMOA.
