Abstract

A q-type Hölder condition on a function f is given in order to establish (uniform) convergence of the corresponding basic Fourier series Sq[f] to the function itself, on the set of points of the q-linear grid. Furthermore, by adding other conditions, one guarantees the (uniform) convergence of Sq[f] to f on and “outside” the set points of the q-linear grid.
