关于微分算子的超循环向量集

On the set of hypercyclic vectors for the differentiation operator

Stanislav Shkarin

摘要:

令$D$是微分算子$Df=f'$作用在具有标准(紧开)拓扑的所有单变量整函数的Fréchet空间$\H$上。自20世纪50年代以来,已知算子$D$的超循环向量集$H(D)$是非空的。我们对待两个问题所提出的Aron,Conejero,Peris和Seoane塞普尔韦达是否集合$H(D)$包含(直到零函数)的非平凡子代数的$\H$或无限维封闭线性子空间的$\H$。在本文中,这两个问题都得到了肯定的回答。

英文摘要:

Let $D$ be the differentiation operator $Df=f'$ acting on the Fréchet space $\H$ of all entire functions in one variable with the standard (compact-open) topology. It is known since 1950's that the set $H(D)$ of hypercyclic vectors for the operator $D$ is non-empty. We treat two questions raised by Aron, Conejero, Peris and Seoane-Sepúlveda whether the set $H(D)$ contains (up to the zero function) a non-trivial subalgebra of $\H$ or an infinite dimensional closed linear subspace of $\H$. In the present article both questions are answered affirmatively.
