Galois theory

In mathematics, Galois theory, originally introduced by Évariste Galois, provides a connection between field theory and group theory. This connection, the fundamental theorem of Galois theory, allows reducing to group theory certain problems in field theory; this makes them simpler in some sense, and allows a better understanding. Galois' work was published fourteen years after his death by Joseph Liouville. The theory took longer to become popular among mathematicians and to be well understood. Galois theory has been generalized to Galois connections and Grothendieck's Galois theory.
