Estimates of orthoprojection widths of classes $B^{\Omega}_{p,\theta}$ of periodic functions of several variables with given majorant of mixed moduli of continuity

We obtain exact order estimates of approximation of classes $B^{\Omega}_{p,\theta}$ of periodic functions of several variables in the space $L_q$ by using operators of orthogonal projection as well as linear operators subjected to some conditions
