Abstract

In this paper two generalized theorems on the degree of approximation of conjugate functions belonging to the Lipschitz classes of the type $\text{Lip}\alpha$, $0<\alpha \leq 1$, and $W(L_{p},\xi (t))$ are proved. The first one gives the degree of approximation with respect to the $L_{\infty}$-norm, and the second one with respect to $L_{p}$-norm, $p\geq 1$. In addition, a correct condition in proving of the second mentioned theorem is employed.
