Group theorists are mathematicians who specialize in the study of group theory, a branch of abstract algebra that focuses on the algebraic structures known as groups. A group is a set accompanied by an operation that combines any two elements to form a third element, satisfying certain axioms: closure, associativity, the existence of an identity element, and the existence of invertible elements.
