Divergent Walsh-Fourier Series. Almost Everywhere Convergence of Walsh-Fourier Series of L2 FunctioIn Chapter 2 we saw that even for a continuous function it is necessary to impose additional conditions to insure that its Walsh- Fourier series converges at every point. Without such conditions, as we remarked in §2.3, the Fourier series of a continuous function may diverge at some points.
