CORRECTION

In my article (M. A. Veliev, “Investigation of the stability of the Bubnov–Galerkin method for nonstationary problems”), published in DAN, vol. 157, No. 1, 1964, the following corrections must be made.

1) In the statements of Theorems 1, 2, 3, and 5, the requirement that the coordinate system be normal must be replaced by the requirement that it be orthonormal.

2) In Theorem 3, stability may be asserted not on an infinite interval, but only on any finite interval of time, and the condition

\[ \int_{0}^{\infty} t^{2}\|f\|^{2}\,dt < +\infty \]

turns out to be superfluous.
