CORRECTIONS

In my article (E. V. Zolotareva, “A Necessary and Sufficient Condition for the Fredholm Property of the Dirichlet Problem for a Certain Class of Elliptic Systems”), published in DAN, vol. 145, no. 4, 1962, Theorem 2 was formulated incorrectly. This theorem is valid only for a special class of domains with analytic boundaries.

In our article (G. A. Kurchi, A. V. Iogansen, “On the Gas-Chromatographic Determination of the Solubility of Gases and Vapors in Liquids”), published in DAN, vol. 145, no. 5, 1962, on p. 1085 formula (1) should read:

\[ K=\frac{t_g' V_0 \rho}{W}. \]
