In our article, published in DAN, vol. 112, no. 5, 1957 (M. A. Proskurnin, Yu. L. Khmel’nitskii, E. V. Barelko, A. T. Slepneva, and I. I. Melekhonova, “The Action of $\gamma$-Radiation on the Oxidation Reaction of Cetane”), on p. 888 the caption to Fig. 3 should read:

Formation of nonvolatile carbonic 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 DAN, 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.
