In the article by L. G. Mikhailov, “Investigation of One Type of Two-Dimensional Integral Equations,” published in DAN, vol. 119, no. 1, 1958:

On p. 29, line 7, printed: “the condition is satisfied”; it should read: “the condition is met.”

On p. 29, line from the bottom, printed: “Theorem 6. If (K(z)) is continuous at the point (z=0),” it should read: “Theorem 6. If (K(z)) is bounded at the point (z=0).”

In my article published in DAN, vol. 120, no. 2, 1958 (A. D. Lyashko, “On the Convergence of Methods of Galerkin Type”), the equality (|\psi|=1) should be postulated, and the norm for the space (Y) should be introduced as follows: (|y|=|x|), (y=Ax), (x\in X).
