The Fourier transform of sinx/x and (sinx/x)^2 and more
In this post we compute the Fourier transform of $\sin{x}/x$ and $(\sin{x}/x)^2$ through contour integration.

The Riesz-Markov-Kakutani Representation Theorem
In this post we develop a proof of the Riesz-Markov-Kakutani theorem on a locally compact Hausdorff space, which is the essential of the existence of the Lebesgue measure.
