Fourier Sequence Converges Uniformly Implies Almost Everywhere Pointwise Convergence

192 Views Asked by At

I'm trying to understand this problem: Let $f$ be Riemann integrable on $[0,2\pi]$

Suppose that the Fourier Series of $f$, $S_{n}^{f}(x)$, converges uniformly on the interval.

I want to show that $S_{n}^{f}(x)\to f(x)$ point-wise almost everywhere.

My attempt:

Since $S_{n}^{f}(x)$ converges uniformly, and $S_{n}^{f}(x)$ is continuous then it holds that $S_{n}^{f}(x) \to g(x)$ uniformly for $g$ continuous.

Then clearly $S_{n}^{f}(x_{0})$ converges to $g(x_{0})$ everywhere on the interval.

Also, since by definition $\int (S_{n}^{f}(x)-f(x)^2dx \to 0$

then $\int (lim_{n\to \infty}S_{n}^{f}(x)-f(x)^2dx = 0 = \int (g(x)-f(x)^2dx$

thus $g=f$ almost everywhere.

Is this reasoning correct?

thanks!
