Estimates for the best bilinear approximations of the classes $B^r_{p,\theta}$ and singular numbers of integral operators

We obtain the exact-order estimates for the best bilinear approximations of the Nikol‘ski–Besov classes $B^r_{p,\theta}$ of periodic functions of several variables. We also find the orders for singular numbers of the integral operators with kernels from the classes $B^r_{p,\theta}$.
