In this paper, we introduce a new concept, ( α , β ) -mean Li–Yorke chaotic operator, which includes the standard mean Li–Yorke chaotic operators as special cases. We show that when α < 1 ≤ β or α ≤ 1 < β , ( α , β ) -mean Li–Yorke chaotic dynamics is strictly stronger than the ones that appeared in mean Li–Yorke chaos. When α > 1 or β < 1 , it has completely different characteristics from the mean Li–Yorke chaos. We prove that no finite-dimensional Banach space can support ( α , β ) -mean Li–Yorke chaotic operators. Moreover, we show that an operator is ( α , β ) -mean Li–Yorke chaos if and only if there exists an ( α , β ) -mean semi-irregular vector for the underlying operator, and if and only if there exists an ( α , β ) -mean irregular vector when α ≤ 1 , which generalizes the recent results by Bernardes et al. given in 2018. When α > 1 , we construct a counterexample in which it is an ( α , β ) -mean Li–Yorke chaotic operator but does not admit an ( α , β ) -mean irregular vector. In addition, we show that an operator with dense generalized kernel is ( α , β ) -mean Li–Yorke chaotic if and only if there exists a residual set of ( α , β ) -mean irregular vectors, and if and only if there exists an β -mean unbounded orbit.

Banach空间上线性算子的(α,β)-Mean Li-Yorke混沌特征
在本文中,我们引入了一个新概念,( α , β ) -mean Li-Yorke 混沌算子,包括标准均值 Li-Yorke 混沌算子作为特例。我们证明当α < 1 ≤ β 要么α ≤ 1 < β ,( α , β ) -mean Li-Yorke 混沌动力学严格地强于出现在平均 Li-Yorke 混沌中的动力学。什么时候α > 1 要么β < 1 ,它与平均的 Li-Yorke 混沌具有完全不同的特征。我们证明没有有限维 Banach 空间可以支持( α , β ) -mean Li-Yorke 混沌算子。此外,我们证明了一个算子是( α , β ) -mean Li-Yorke 混沌当且仅当存在( α , β ) - 基础运算符的均值半不规则向量,并且当且仅当存在( α , β ) -mean 不规则向量当α ≤ 1 ,它概括了 Bernardes 最近的结果等。 在 2018 年给出。当α > 1 ,我们构造一个反例,其中它是( α , β ) -mean Li-Yorke 混沌算子但不承认( α , β ) -均值不规则向量。此外,我们证明了具有密集广义核的算子是( α , β ) -mean Li-Yorke 混沌当且仅当存在残差集( α , β ) -均值不规则向量,且当且仅当存在β - 平均无界轨道。
