论文摘要
我们表明,Dirichlet系列的Wiener代数上有界组成算子的象征不需要属于该代数。我们的示例甚至给出了一个绝对的总结(因此是紧凑的)构图操作员。
We show that the symbol of a bounded composition operator on the Wiener algebra of Dirichlet series does not need to belong to this algebra. Our example even gives an absolutely summing (hence compact) composition operator.
