Errata to the article by A. G. Lomagin «Resistance of vegetable cells to sodium azide, as influenced by thermal hardening» («Doklady», vol. 147, No. 3 (1962)).

CORRECTION

In our article (E. I. Zverovich and G. S. Litvinchuk, “On one-sided boundary value problems of the theory of analytic functions”), published in DAN, vol. 145, No. 2, 1962, condition (8) should be replaced by the following:

\[ 1)\quad \sum_k |a_k\lambda_k|^2 < \infty, \qquad 2)\quad \sum_k a_k\mu_k(s)=f[t(s)], \]

where \(\{\lambda_k^2\}\) is the system of eigenvalues of the kernel \(K_L\).
