Classification of Groups Groups may be Finite or Infinite; that is, they may contain a finite number of elements, or an infinite number of elements Also, groups may be Commutative or Non-Commutative, that is, the commutative property may or may not apply to all elements of the group.
For example Abelian groups are named after Neils Abel, a Norwegian mathematician. Properties of Modular Arithmetic Addition works just as if it was a normal equality. SIZE — 6. PAGES — In mathematics, a group is a set equipped with a binary operation that combines any two elements to form a third element in such a way that four conditions called group axioms are satisfied, namely closure, associativity, identity, and invertibility. One of the most familiar examples of a group is the set of integers together with the addition operation, but groups are encountered in numerous areas within and outside mathematics and help to focus on essential structural aspects, by detaching them from the concrete nature of the subject of the study.
Groups share a fundamental kinship with the notion of symmetry. For example, the asymmetry group encodes symmetry features of a geometrical object: the group consists of the set of transformations that leave the object unchanged and the operation of combining two such transformations by performing one after the other.
After contributions from other fields such as number theory and geometry, the group notion was generalized and firmly established around Modern group theory—an active mathematical discipline—studies groups in their own right. To explore groups, mathematicians have devised various notions to break groups into smaller, better-understandable pieces, such as subgroups, quotient groups, and simple groups.
In addition to their abstract properties, group theorists also study the different ways in which a group can be expressed concretely, both from a point of view of representation theory that is, through the representations of the group and of computational group theory. A theory has been developed for finite groups, which culminated with the classification of finite simple groups, completed in True or False. Every Diagonalizable Matrix is Invertible.
