The history of group theory, a mathematical domain studying groups in their various forms, has evolved in various parallel threads. There are three historical roots of group theory: the theory of alge

Évariste Galois was a French mathematician and political activist. While still in his teens, he was able to determine a necessary and sufficient condition for a polynomial to be solvable by radicals,
History of group theory
…roots of group theory: the theory of algebraic equations, number theory and geometry. Joseph Louis Lagrange, Paolo Ruffini, Niels Henrik Abel and Évariste Galois were early researchers in the field of group theory. The earliest study of groups as such probably goes back to the work of Lagrange in the late 18th…
