摘要
It is known that a sense preserving homeomorphism h of the unit circle induces a BMO map P-h by pull-back if and only if it is strongly quasisymmetric. In this note, we will discuss the compactness of the projection operator P-h(-) sending a BMOA function phi to the anti-holomorphic part of P-h phi.
