  Evariste Galois
Evariste Galois (1811 1832) was a mathematician whose genius engendered innovative ideas and inventive approaches.
Evariste was born in Bourg-La-Reine on the 25th of October in 1811 to Nicholas-Gabriel Galois and Adelaide-Marie Demante.
However, Galois was arrested again on Bastille Day 1831 for possessing a weapon and wearing the uniform of the Guard, which had been ordered disbanded by a fearful Louis-Philippe.

Galois theory is that branch of abstract algebra which studies the symmetries of the roots of polynomials.
Symmetries are usually expressed in terms of symmetry groups, and in fact the abstract notion of group was invented by Evariste Galois for the very purpose of describing symmetries of roots.
In the modern approach, the formalism is changed somewhat, in order to achieve a precise and more general definition: one starts with a field extension L/K and defines its Galois group as the group of all field automorphisms of L which keep all elements of K fixed.

 .:: Galois Field Arithmetic Library ::.
The branch in mathematics known as Galois theory (pronounced as "gal-wah") which is based on abstract algebra was discovered by a young brilliant french mathematician known as Evariste Galois.
Galois field polynomials within the branch are seen as mathematical equivalents of Linear Feed-Back Shift Register (LFSR) and operations upon elements are accomplished via bitwise operations such as xor, and, or logic.
Galois theory is used to describe and generalize results seen in these fields, for example the AES algorithm can be represented with just a few lines of mathematics using Galois theory and some other related abstract algebra.

Evariste Galois (October 25, 1811-May 31, 1832) was a French mathematician born in Bourg-la-Reine.
His work laid the fundamental foundations for Galois theory, a major branch of abstract algebra and of pseudorandom sequence (PN) and error-correction coding applications.
The night before the duel, supposedly fought in order to defend the honor of a woman, he was so convinced of his impending death that he stayed up all night writing letters to his Republican friends and composing what would become his mathematical testament.

 Evariste Galois' Biography   (Site not responding. Last check: 2007-11-07)
Galois theory is essentially the "complete" theory of the roots of polynomial equations in one variable.
Galois' brilliant insight was that one can know essentially "everything" there is to know about the roots of polynomial equations by considering a new object, a group, namely the group of all "reasonable" permuations of those roots.
Galois concluded that not all permutations of the roots of a polynomial may be reasonable.

Since it was opened, EVARISTE delivered an on-line version of the output of a recent work achieved by the French ministry of Industry, entitled "100 key technologies", which provides an analysis grid, for public authorities as well as for industrial managers, exploring forces and weaknesses of the French industry and research achievements.

This article is not intended to examine the work of Galois but rather to consider the extraordinary times that Galois lived in and to show the influence of world events on mathematics.
From this point the monarchy of Louis 16th was in major difficulties as the majority of Frenchmen composed their differences and united behind an attempt to destroy the privileged establishment of the church and the state.
However in 1826 Galois was asked to repeat the year because his work in rhetoric was not up to the required standard.

 Galois Groups
The Galois group of the polynomial is then the group G of automorphisms of E that leave F fixed.
The preceding definition of a Galois group is actually a modernized version introduced by Emil Artin in the late 1920's (based on the earlier ideas of Emmy Noether and Richard Dedekind).
This, therefore, is the Galois group of the preceding polynomial relative to the coefficient field Q. One of the most important applications of Galois theory (indeed, the reason it was invented) is to provide the criterion for deciding when a polynomial is solvable by means of rational operations and root extractions.

His theory provided a solution to the long-standing question of determining when an algebraic equation can be solved by radicals (a solution containing square roots, cube roots, and so on but no trigonometry functions or other nonalgebraic functions).
Rather than establishing whether specific equations can or cannot be solved by radicals, as Abel had suggested, the French mathematician Évariste Galois (1811–32) pursued the somewhat more general problem of defining necessary and sufficient conditions for the solvability of any given equation.

 Evariste Galois: intro
Evariste Galois is undoubtedly the father of modern algebra.
But as soon as you start working seriously on the story of his life, you realize how many details are missing, blurred or in the worst case even distorted.
Another problem lies in the fact, that most of the original texts of Evariste Galois are not easily available, if you are not in working distance of Paris or at least a university with a huge library.

But when he first encountered Galois theory as a Yale graduate student fourteen years ago, was overwhelmed by the degree of abstraction.
Evariste Galois was a brilliant young French mathematician of the early 19th century, and his point of view on roots of polynomials inspired the theory that now bears his name.
But with the increasing power of computing, Galois theorists gained the ability to perform calculations and understand examples that had been inaccessible with pencil and paper.
