Abstract

Finite dimensional simple and semi-simple Lie algebras will be categorized with the help of Hasse diagrams and Cartan matrices. These results will be used in the construction of a very specific Kac-Moody algebra: the affine Lie algebra. This infinite dimensional highly structured Lie algebra can be constructed using the generalized Cartan matrix. An affine Lie algebra is closely related to a semi-simple Lie algebra. The affine Lie algebra can be roughly be seen as an infinite tower of a semi-simple Lie algebra. This means that an affine Lie algebra can be constructed as the affine extension of a semi-simple Lie algebra. Lie algebras appear in a slightly different manner in physics. They are closely related to symmetries. A close look at space-time symmetries and supersymmetry will result in a Super-Poincar'e algebra. Supersymmetry can then be gauged to construct a supergravitational theory. Maximal supergravity is a supergravity theory with as many supersymmetry generators as physically possible. It can most easily be obtained by Kaluza-Klein dimensional reduction of eleven dimensional supergravity.
