Abstract:For the open unit disc in the complex plane, it is well known that if then its Berezin transform also belongs to . We say that is BC-regular. In this paper we study BC-regularity of some pseudoconvex domains in and show that the boundary geometry plays an important role. We also establish a relationship between the essential norm of an operator in a natural Toeplitz subalgebra and its Berezin transform.

摘要:对于复平面中的开放单位圆盘,众所周知,如果它的Berezin变换也属于。我们说这是BC常规的。在本文中,我们研究了其中某些伪凸域的BC正则性,并证明边界几何起着重要作用。我们还建立了自然Toeplitz子代数中算子的基本范数与其Berezin变换之间的关系。
