In our article, printed in Doklady Akademii Nauk, vol. 112, no. 5, 1957 (M. A. Proskurnin, Yu. L. Khmel’nitskii, E. V. Barelko, A. T. Slepneva, and I. I. Melekhonova, “The effect of γ-radiation on the oxidation reaction of cetane”), on p. 888 the caption to Fig. 3 should read:

Formation of nonvolatile carboxylic acids as a function of time under the action of various radiation doses (integral doses, kg): 1 — 576; 2 — 144; 3 — 864; 4 — 288; 5 — 72; 6 — without irradiation.

In the article by Yu. S. Bogdanov, “Lyapunov Norms in Linear Spaces,” published in Doklady Akademii Nauk, vol. 113, no. 2, 1957:

a) On p. 257, the last phrase of item 15° should read: In this case the second ([\lambda'']) norm refines the first ([\lambda']), i.e.

[
\lambda'' a \leq \lambda'' a' \to \lambda' a \leq \lambda' a', \quad
\lambda'' a = \lambda'' a' \to \lambda' a = \lambda' a'.
]

b) In the list of cited literature, item 3 should read: A. M. Lyapunov, see (1), p. 39.
