ERRATA

In the article by Kh. N. Zeitunian, “On the nonlinear theory of a nonstationary skew wind,” published in DAN, vol. 133, No. 6, 1960:

On p. 1320, formula (12), instead of \((\xi-\varepsilon')^m\), one should read \((\xi-\zeta')^m\).

On p. 1321, formula (16), instead of

\[ \sum_{k=2}^{r} 2^{k-1}(r-1)(r-1)\ldots \]

one should read

\[ \sum_{k=2}^{r} 2^{k-1}(r-1)(r-2)\ldots \]

On p. 1321, formula (19), instead of \(+4\Gamma^2\chi^3 F_{n-8} W_{n,2}\) one should read

\[ +5\Gamma^2\chi^4 F_{n-8} W_{n,2}. \]

In our article (V. M. Darevskii and R. I. Kishniakin, “Stability of a cylindrical shell reinforced with rings under the action of external pressure”), published in DAN, vol. 134, No. 3, 1960, on p. 549, line 14, instead of \(k = 1 + (1+h/H)/[h/H+\chi a/2R]\) it should be \(k = 1 + (1-h/H)/(h/H+\chi a/2R)\).
