Group representations in mathematics are a key concept in understanding the symmetry and structure of algebraic objects. By mapping group elements to matrix operations, they enable the use of linear algebra to analyze group properties. This has applications in physics for studying particle symmetries, in chemistry for molecular behavior, and in technology for cryptography and computer graphics. Representation theory, particularly of finite groups and Lie groups, provides insights into the nature of these groups and their continuous transformations.
