Abstract:
Let $G$ be an infinite countable discrete amenable group. For any $G$-action on a compact metric space $(X,\rho)$, it turns out that if the action has positive topological entropy, then for any sequence $\{s_i\}_{i=1}^{+\infty}$ with pairwise distinct elements in $G$ there exists a Cantor subset $K$ of $X$ which is Li–Yorke chaotic along this sequence, that is, for any two distinct points $x,y\in K$, one has
$$
\limsup\limits_{i\to+\infty}\rho(s_i x,s_iy)>0,\ \text{and}\ \liminf_{i\to+\infty}\rho(s_ix,s_iy)=0.
$$
Key words and phrases:
Li–Yorke chaos, topological entropy, measure-theoretic entropy, amenable group action.
