Best Answer

Evariste Galois lived from 1811 till 1832. He died in a duel in Mary of 1832. He did not study mathematics at all until 1827 and appears to have concentrated on group theory in 1832.

It was Évariste Galois (1811 -- 1832) who discovered that there exists a radical expression for the roots if and only if the Galois group of the polynomial - initially a permutation group on the roots - is solvable Galois97.

This was first discovered by Evariste Galois not long before his death at the age of 20 in 1832. He found that any polynomial of degree greater than 4 cannot have a general solution in terms of radicals. A field of abstract algebra evolved from his work, and is known as Galois theory.

In group theory, an alternating group is a group of even permutations of a finite set.

Theory X is a group of ideas created by Douglas McGreggor in the 1960's. It deals with human motivations. He also discussed theory

Many consider him the father of modern algebra. Galois theory was named after him and is very important for many reasons one of which is it provides a connection between field theory in modern algebra and group theory.

he discovered it in 1823

The galois theory is used to solve radicals. this is spectre, signing off

The initial work on Group Theory was carried out by Evariste Galois, but sadly heis work was not accepted by mathematicians of the time and was published only after his death (1832).

1832 is when he wrote about the groupl theory.

There sure is, and a major connection at that.Consider a finite set of n elements. The symmetric group of this set is said to have a degree of n. The symmetric group of degree n (Sn) is the Galois group of the general polynomial of degree n. In order for there to be a formula involving radicals that solve the general polynomial of degree n, such as the quadratic equation when n = 2, that polynomial's corresponding Galois group must be solvable. S5 is not a solvable group. Therefore, the Galois group of the general polynomial of degree 5 is not solvable. Thus the general polynomial of degree 5 has no general formula to solve it using radicals.This was huge result, and one of the first real applications, for group theory, since that problem had stumped mathematicians for centuries.
