2 unusual facts about Galois theory


Constructible polygon

In the light of later work on Galois theory, the principles of these proofs have been clarified.

Endre Boros

In 1986, Boros settled (with T. Szőnyi) a conjecture by Beniamino Segre about the cyclic structure of finite projective planes, and in 1988 provided the best known bound for a question posed by Paul Erdős about blocking sets of Galois planes.


Peter Ludwig Mejdell Sylow

Sylow was a high school teacher in Halden, Norway, from 1858 to 1898, and a substitute lecturer at Christiania University in 1862, covering Galois theory.
