The best trigonometric and bilinear approximations of the functions of many variables from the classes $B_{p,\theta}^r$. I
Approximations are studied of the classes $B_{p,\theta}^r$of periodic functions of several variables with the help of trigonometric polynomials with a given number of harmonics. The results obtained are used to establish order estimates of the approximation of functions of the form $f(x - y)$, $f (x...
