Li-Yorke chaos translation set for linear operators (1712.02580v1)

Abstract: In order to study Li-Yorke chaos by the scalar perturbation for a given bounded linear operator $T$ on Banach spaces $X$, we introduce the Li-Yorke chaos translation set of $T$, which is defined by $S_{LY}(T)={\lambda\in\mathbb{C};\lambda+T \text{ is Li-Yorke chaotic}}$. In this paper, some operator classes are considered, such as normal operator, compact operator, shift and so on. In particular, we show that the Li-Yorke chaos translation set of Kalisch operator on Hilbert space $\mathcal{L}^2[0,2\pi]$ is a simple point set ${0}$.
