The representation theory of semisimple Lie algebras is one of the crowning achievements of the theory of Lie groups and Lie algebras, and is also known as the Cartan–Weyl theory. By replacing matrix multiplication with the matrix commutator, the n × n matrices become a Lie algebra, leading to a representation theory of Lie algebras.3 Sources - See moreSee all on Wikipedia

- Very roughly speaking, representation theory studies symmetry in linear spaces. It is a beautiful mathematical subject which has many applications, ranging from number theory and combinatorics to ge-ometry, probability theory, quantum mechanics, and quantum eld theory. Representation theory was born in 1896 in the work of the Ger-man mathematician ...
