In Subsects. 3.2 and 3.3, pages 541–543, it is implicitly assumed that \(\epsilon \ne 0\). This hypothesis should have been explicitly stated. Similarly, on page 552, in the sentence above Theorem 4.2, the hypothesis should be \(\epsilon \in \mathbb {R} \setminus \{0\}\). The case \(\epsilon = 0\) is not considered in the paper; it was carried out, by hand, only for the system in Example 3.1, pages 544–545.
