WebMore directly, one way to derive Kakeya estimates (which are often somewhat weaker versions of the Kakeya conjecture) would be to apply Fourier decompositions (e.g. separate low frequencies from high frequencies) to functions f which are given by the sum of indicator functions of tubes.

WebYou are integrating over the interval from -pi to pi, which is compact. The only way a simple function could be not integrable over that interval would be if it were unbounded. The signum function is bounded. The easiest way to find this fourier series would be to use the definition of the fourier series and the definition of the signum function.

It is given by ˆf(k) = ∫∞ − ∞f(x)eikxdx = ∫a − abeikxdx = b ikeikx a − a = 2b k sinka. We can rewrite this as ˆf(k) = 2absinka ka ≡ 2absinc ka. Here we introduced the sinc function sinc x = sinx x. A plot of this function is shown in Figure 9.5.4.
