WebJul 19, 2024 · But in 1832 the young mathematician Évariste Galois discovered the search was fruitless, proving that there are no general methods for calculating the roots of higher-power polynomials. Galois didn’t stop there, though. In the months before his death in a duel in 1832 at age 20, Galois laid out a new theory of polynomial solutions. suzuki vitara 2015 specs

Possibly, H. W. Lenstra's Galois theory for schemes might be of interest to you. In my very humble opinion, this is a very hard topic to find a solid book on. Lenstra's text is very feel-good, but has serious drawbacks. It does everything very old fashioned. For example, Lenstra thinks of curve theory in terms of valuation theory.
