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 certain problems in field theory to group theory, which makes them simpler and easier to … See more The birth and development of Galois theory was caused by the following question, which was one of the main open mathematical questions until the beginning of 19th century: Does there exist a … See more Pre-history Galois' theory originated in the study of symmetric functions – the coefficients of a monic polynomial See more In the modern approach, one starts with a field extension L/K (read "L over K"), and examines the group of automorphisms of L that fix K. See the … See more The inverse Galois problem is to find a field extension with a given Galois group. As long as one does not also specify the ground field, … See more Given a polynomial, it may be that some of the roots are connected by various algebraic equations. For example, it may be that for two of the roots, say A and B, that A + 5B = 7. … See more The notion of a solvable group in group theory allows one to determine whether a polynomial is solvable in radicals, depending on whether its Galois group has the property of solvability. In essence, each field extension L/K corresponds to a factor group See more In the form mentioned above, including in particular the fundamental theorem of Galois theory, the theory only considers Galois extensions, which are in particular separable. General field extensions can be split into a separable, followed by a purely inseparable field extension See more WebApr 9, 2015 · In 1928, while Galois was seventeen years old, he failed the entrance examination to the École Polytechnique, the most prestigious institute of mathematics in France at the time. He instead attended The École Normale. While here, he began making fundamental discoveries related to the theory of polynomials and submitted two papers … midnight music lyrics
