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

Joseph Liouville was a French mathematician who worked on a number of different fields in mathematics, including number theory, complex analysis, and mathematical physics. Many mathematical concepts a

…of constructible polygons was complete; all known proofs that this characterization is complete require Galois theory). Galois' work was published by Joseph Liouville fourteen years after his death. The theory took longer to become popular among mathematicians and to be well understood. Galois theory has been generalized…
