论文摘要
我们为在聚盘的伯格曼空间上的一类Hankel操作员的Hermitian广场提供了足够的条件,以包含间隔。我们还计算频谱,以防符号是单一的。
We give sufficient conditions for the essential spectrum of the Hermitian square of a class of Hankel operators on the Bergman space of the polydisc to contain intervals. We also compute the spectrum in case the symbol is a monomial.
