Correction to: Acta Mech https://doi.org/10.1007/s00707-022-03319-y

In the version of the article originally published, Eq. (28) was shown incorrectly. Equation (28) is corrected as:

$$\begin{aligned} \begin{aligned} {\bar{A}}_1&=\dfrac{{\bar{\gamma }}_2}{[{\bar{\gamma }}]}{\bar{U}}_1(0)+\dfrac{i}{[{\bar{\gamma }}]}{\bar{T}}_2(0),\,{\bar{A}}_2=\dfrac{i{\bar{\beta }}_2}{[{\bar{\alpha }};{\bar{\beta }}]} {\bar{U}}_2(0)+\dfrac{{\bar{\alpha }}_2}{[{\bar{\alpha }};{\bar{\beta }}]} {\bar{T}}_1(0),\\ {\bar{A}}_3&=-\dfrac{{\bar{\gamma }}_1}{[{\bar{\gamma }}]} {\bar{U}}_1(0)-\dfrac{i}{[{\bar{\gamma }}]} {\bar{T}}_2(0),\,{\bar{A}}_4=-\dfrac{i{\bar{\beta }}_1}{[{\bar{\alpha }};{\bar{\beta }}]} {\bar{U}}_2(0)-\dfrac{{\bar{\alpha }}_1}{[{\bar{\alpha }};{\bar{\beta }}]} {\bar{T}}_1(0). \end{aligned} \end{aligned}$$

Several equations were cited incorrectly. Their correct cited numbers are: (27.1,2,3,4) (line 19, page 6), (14.1,2) (line 2 from the bottom of page 6), (14.1) (line 10 of page 7), (19.1,2) (line 17 of page 7), (35) and (41) (line 4 from the bottom of page 7), (54.1,2,3,4,5) (line 3 of page 11), (54.1,2,3,4,5) and (61) (line 18 of page 11).

These corrections do not affect any of the results or other expressions reported in the paper.

The original article has been corrected.
