关于超递归算子
On super-recurrent operators
摘要:
本文引入并研究了算子超常返的概念。我们研究了这类算子的一些性质,并证明了它与超循环算子和常返算子有一些共同的性质。特别是,我们表明,如果$T$是超递归的,那么$σ(T)$和$σ_p(T^*)$,$T$的谱和$T^*$的点谱,分别有一些值得注意的性质。
英文摘要:
In this paper, we introduce and study the notion of super-recurrence of operators. We investigate some properties of this class of operators and show that it shares some characteristics with supercyclic and recurrent operators. In particular, we show that if $T$ is super-recurrent, then $σ(T)$ and $σ_p(T^*)$, the spectrum of $T$ and the point spectrum of $T^*$ respectively, have some noteworthy properties.
