Correction to: J Dyn Control Syst
The original version of this article unfortunately contained a mistake.
In the second paragraph of Definition 2.4, we defined elements x and y to be asymptotic if for any \(U\in \mathcal {U}\) and any \(\{G_{i}|i \in \mathbb {N}\} \in \mathcal {G}\), there exists \(k \in \mathbb {N}\) such that (gx,gy) ∈ U for each g ∈ G∖Gk. However, this definition is incorrect, because it holds that x and y are asymptotic if and only if x = y. Thus the second paragraph of Definition 2.4 needs to be corrected as follows:
Elements x and y of X to be asymptotic if for any \(U \in \mathcal {U}\) and any \(\{G_{i} |i \in \mathbb {N}\}\in \mathcal {G}\), there exists \(k \in \mathbb {N}\) such that (gx,gy) ∈ U for each \(g\in \bigcup _{i\in \mathbb {N}} G_{i} \backslash G_{k} \).
And the set AR of the forth paragraph of Definition 2.4 should be denoted by
Along with the above corrections, we need to correct as follows:
-
The phrase “let G be an Abelian group” in the statement of Theorem 1.2 is replaced by “let G be a countable Abelian group”. Similarly, the phrases “an Abelian group G” in Lemma 3.6 and Proposition 3.7 are replaced by “a countable Abelian group G”.
-
In the proof of Lemma 3.6, the phrase “Let \((G_{i})_{i\in \mathbb {N}}\) be an elements of \(\mathcal {G}\) with G1 = ∅” of the line 1 in the second paragraph should be replaced by “Let \((G_{i})_{i\in \mathbb {N}}\) be an elements of \(\mathcal {G}\) with G1 = ∅ and \(G=\bigcup _{i\in \mathbb {N}} G_{i} \)”.
