Оказывается, есть смысл рассматривать категорию Банаховых пространств с равномерно непрерывными морфизмами вместо линейных. Это типо полезно даже...

«Researchers studying the inverse Galois problem realized 25 of the 26 sporadic finite simple groups as Galois groups over ℚ during 1984--1989. We complete this program by proving that the last remaining sporadic group, the Mathieu group M23, occurs as a Galois group over ℚ. In fact, we produce an explicit degree 23 polynomial with rational coefficients whose splitting field has Galois group M23 over ℚ. To accomplish this, we use a non-rigid triple of conjugacy classes of M23 and compute Belyi maps to construct an explicit regular Galois extension of ℚ(t) with Galois group M23. Essential for our computation is the numerical Belyi map algorithm developed and implemented by Klug, Musty, Schiavone, Sijsling, and Voight, inspired by ideas of Hejhal and Stark.»
