证明了有界算子SonLapforp> 1是紧的当且仅当S的Berezin变换在单位圆盘的边界上为零且满足一定的可积条件.得到了BT中带符号的Toeplitz算子的范数和本质范数的一些估计。
We prove that a bounded operatorSonLapforp> 1 is compact if and only if the Berezin transform ofSvanishes on the boundary of the unit disk ifSsatisfies some integrable conditions. Some estimates about the norm and essential norm of Toeplitz operators with symbols in BT are obtained.
