The theorem was proven independently in 1907 by Frigyes Riesz and Ernst Sigismund Fischer. For many authors, the Riesz–Fischer theorem refers to the fact that the Lp spaces from Lebesgue integration theory are complete. comic market 85

"Tīmeklis3 Fejer’s Theorem The last theorem of the preceding section may be re-stated as: \The sym-metric partial sums of the Fourier series of an L2 function converge to the function in the L2 norm." In many ways this is the most natural sense of convergence for an L2 func- tion’s Fourier series, but there is a more basic form of convergence that " - Fejer riesz
