AB - In the space $L_2$, we determine the exact values of some $n$-widths for the classes of functions such that the generalizedmoduli of continuity of their $(\psi, \beta)$ - derivatives or their averages with weight do not exceed the values of the majorants $\Phi$ satisfying certain conditions. Specific examples of realization of the obtained results are also analyzed.
