A field is a ring where 16= 0, and where for all x6=0, there exists ywith xy= 1. The group´ associated to the differential equation is in this case a linear algebraic group and a characterization of equations solvable by quadratures is given in terms of the Galois group. A Classical Introduction to Galois Theory develops the topic from a historical perspective, with an emphasis on the solvability of polynomials by radicals. The central idea of Galois' theory is to consider permutations (or rearrangements) of the roots such that any algebraic equation satisfied by the roots is still satisfied after the roots have been permuted. Originally, the theory had been developed for algebraic equations whose coefficients are rational numbers. • GALOIS (noun) The noun GALOIS has 1 sense: 1. French mathematician who described the conditions for solving polynomial equations; was killed in a duel at the age of 21 (1811-1832) Familiarity information: GALOIS used as a noun is very rare.

Introduction The question of whether all nite groups can occur as Galois groups of an extension of the rationals (known as the inverse problem of Galois theory) is still unsolved, in spite of substantial progress in recent years. In retrospect, this was the birth of Group Theory. It is often convenient to use these facts to interpret elements of the Galois group as permutations of the roots of some polynomial which splits over E. 4.5.

The celebrated criterion due to Galois for the solvability of polynomials by radicals is … the theorem is proved for fields of characteristic 0 as well as other fields. 1.2 Galois fields If p is a prime number, then it is also possible to define a field with pm elements for any m. These fields are named for the great French algebraist Evariste Galois who was killed in a duel at age 20. Hall. A generalization of Abel's approach, which was ap­ plicable to all polynomial equations, was found a few years later by the twenty-year-old Evariste Galois (1811-1832).
