On the degree of approximation of functions belonging to the Lipschitz class. (English) Zbl 0774.42005
The author defines the almost Euler summability and gives the degree of approximation of the conjugate function of a function belonging to the class $$\text{Lip }\alpha$$, $$0<\alpha\leq 1$$, by the almost Euler means of the conjugate Fourier series.
