Classes of function \(W_{p}^{r}, r=\left(r_{1}, \ldots, r_{n}\right), 1<p<\infty\), with "dominated" mixed derivative are considered. A new formula for the \(K\)-functional of the couple \(\left(L_{p}: W_{p}^{*}\right)\) is proved. The functional spaces generated by the real method of interpolation
