In the article by Yu. K. Dembyanovich, “On estimates of the rate of convergence of certain projection methods for solving elliptic equations,” published in DAN, vol. 174, no. 3, 1967, on p. 520, line 7 from the bottom, where
$W_2^k(Q)$
is printed, one should read
$W^k(Q)$.
In the article by M. I. Morozov, “On the question of uniform approximation of functions by positive linear operators,” published in DAN, vol. 172, no. 4, 1967, the following corrections must be made:
| Printed | Should read | |
|---|---|---|
| P. 787, line 10 from the bottom | $f(x)=U(x,f,\lambda)=;$ | $f(x)-U(x,f,\lambda)=$ |
| P. 788, line 8 from the bottom | $\lvert f(x)-U(x,f,\lambda);$ | $\lvert f(x)-U(x,f,\lambda)\rvert.$ |
| P. 688, line 14 | $k=2,3;$ | $k=2,3,\ldots,$ |
| P. 788, line 17 | $2\left(1-\dfrac{\lambda_1}{4}-\sum_{k=2}^{\infty}\dfrac{\lambda_k}{k^2-1}\right);$ | $2\left(1-\dfrac{\lambda_1}{4}-\sum_{k=2}^{\infty}\dfrac{\lambda_k}{k^2-1}\right)\sin\theta.$ |
| P. 788, line 10 from the bottom | $k=n,n+1;$ | $k=n,n+1,\ldots$ |
