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 article on Galois groups for further … 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.

WebGALOIS THEORY AT WORK: CONCRETE EXAMPLES 3 Remark 1.3. While Galois theory provides the most systematic method to nd intermedi-ate elds, it may be possible to argue in other ways. For example, suppose Q ˆFˆQ(4 p 2) with [F: Q] = 2. Then 4 p 2 has degree 2 over F. Since 4 p 2 is a root of X4 2, its minimal polynomial over Fhas to be a ... eight animals on the townWebDifferential Galois theory〉, Waldschmidt, Michel; Moussa, Pierre; Luck, Jean-Marc; Itzykson, Claude, 《From number theory to physics.
