We consider the interrelation between the smoothness of a function at a fixed point with the behavior at this point of the Cesàro $(C,\beta)$-means of the Fourier series of this function.
Keywords: pointwise approximation of a function, smoothness of a function, Fourier series, Dirichlet kernel.
Mots-clés : Cesàro means
