Corrected Fourier series and its application to function approximation
International Journal of Mathematics and Mathematical Sciences, 2005 Any quasismooth function f(x) in a finite interval [0,x0], which has only a finite number of finite discontinuities and has only a finite number of extremes, can be approximated by a uniformly convergent Fourier series and a correction function.
