Corrections

In our article (E. P. Zhidkov, I. V. Puzynin, “Solution of boundary-value problems for nonlinear ordinary differential equations of second order by the stabilization method”), published in DAN, vol. 174, no. 2, 1967, the following correction must be made.

On p. 273, lines 6 and 7 should read: the boundary-value problem (v'' + f'_y(x, y(x))\,v = 0), (v(0) = v(1) = 0), has only the trivial solution for any continuously differentiable—

In our article (Yu. G. Borisovich, V. F. Subbotin, “The shift operator along the trajectories of evolutionary equations and periodic solutions”), published in DAN, vol. 175, no. 1, 1967, the following correction must be made.

On p. 12, Theorem 6, it was printed: 3) (\gamma(\theta)) is undefined if (\Delta = 0). It should read: 3) If (\Delta = 0), the index (\gamma(\theta)) is undefined or is equal to zero depending on whether condition (10) is satisfied or not.
