A Lie group is This landmark theory of the 20th Century mathematics and physics gives a rigorous foundation to modern dynamics, as well as field and gauge theories in physics, engineering and biomechanics. In mathematics, a Lie superalgebra is a generalisation of a Lie algebra to include a Z 2 grading.Lie superalgebras are important in theoretical physics where they are used to describe the mathematics of supersymmetry.In most of these theories, the even elements of the superalgebra correspond to bosons and odd elements to fermions (but this is not always true; for example, the Well see that to every root system there corresponds a semisimple Lie algebra, so its important to know all the root systems.
