Contact The Lie Algebras su N ), an Introduction 2003 (revised 2008) ISBN 3-7643-2418-X The su N ) Lie algebras very frequently appear and "there is hardly any student of physics or mathematics who will never come across symbols like su ) and su )" (Fuchs, Schweigert, 1997, p. XV). For instance, the algebra su ) describes angular momenta, su ) is related to harmonic oscillator properties or to rotation properties of systems and su ) represents states of elementary particles in the quark model. This book is mainly directed to undergraduate students of physics or to interested physicists. It is conceived to give directly a concrete idea of the su N ) algebras and of their laws. The detailed developments, the numerous references to preceding places, the figures and many explicit calculations of matrices should enable the beginner to follow. Laws which are given without proof are marked clearly and mostly checked with numerical tests. Knowledge of basic linear algebra is a prerequisite. Many results are obtained, which hold generally for (simple) Lie algebras. Therefore, the text on hand can make the lead-in to this field easier. The structure of the contents is simple. First, Lie algebras are defined and the

In actual fact it is the science which demands the utmost imagination. One of the foremost mathematicians of our century says very justly that it is impossible to be a mathematician without also being a poet in spirit... It seems to me that the poet must see what others do not see, must see more deeply than other people. And the mathematician must do the same. -Sofya Kovalevskaya, 1890

Tony Smith's Home Page What IS a Lie Group? Thanks to John Baez and Dave Rusin for pointing out that this page is a non-rigorous, non-technical attempt at answering the question ONLY for compact real forms of complex simple Lie groups, such as groups of rotations acting on spheres, for which a complete classification is known. There are a lot of Lie groups that are NOT compact real forms of complex simple Lie groups. For instance, the real line with the action of translation is a non-compact Lie group, and solvable Lie groups are certainly not simple groups. An example of a solvable Lie group is the nilpotent Lie group that can be formed from the nilpotent Lie algebra of upper triangular NxN real matrices. So, when you read this page, be SURE to realize that when I say "Lie group", that is my shorthand for "compact real form of a complex simple Lie group", and similar shorthand is being used when I say " Lie algebra As it will turn out that the Lie groups I will discuss are closely related to the division algebras, I will note that you can find a lot about the division algebras on Dave Rusin's division algebra fact page At the end of this page, some miscellaneous related matters are discussed:

A Neighborhood of Infinity Saturday, November 17, 2007 What's all this E8 stuff about then? Part 1. With all the buzz about E8 recently I want to give an introduction to it that's pitched slightly higher than pop science books, but that doesn't assume more than some basic knowledge of geometry and vectors and a vague idea of what calculus is. There's a lot of ground to cover and so I can't possibly tell the truth exactly as it is without some simplification. But I'm going to try to be guilty of sins of omission rather than telling outright lies. Discrete symmetry groups. Consider a perfect cube. If you turn it upside-down it still looks just like a cube in exactly the same configuration. Rotate it through 90 degrees about any axis going through the centre of a face and it looks the same. Rotate it through 120 degrees around a diagonal axis and it also looks the same. In fact there are 24 different rotations, including simply doing nothing, that you can perform on a cube, that leave it looking how you started. (Exercise: show it's 24.) group . The 24 symmetries of the cube form a group of size 24. Although you can think of a group as a bunch of operations on something, you can also think of a group as a thing in its own right, independent of the thing it acts on. For example, we can write down some rules about A, B and C above. AC=CA=1, C=AB, AAB=1, BB=1, C1=1C=C and so on. In principle we can give a single letter name name to each of the 24 symmetries and write out a complete set of rules about how to combine them. At that point we don't need the cube any more, we can just consider our 24 letters, with their rules, to be an object of interest in its own right.

Lie algebra Information about Lie algebra Lie algebra Information about Lie algebra Double click any English word, to find Turkish meaning In mathematics , a Lie algebra is an algebraic structure whose main use is in studying geometric objects such as Lie groups and differentiable manifolds . Lie algebras were introduced to study the concept of infinitesimal transformations . The term "Lie algebra" (after Sophus Lie , pronounced ("lee"), not ("lie") ) was introduced by Hermann Weyl in the . In older texts, the name " infinitesimal group " is used. Definition and first properties A Lie algebra is a type of algebra over a field ; it is a vector space over some field F together with a binary operation called the commutator or the Lie bracket , which satisfies the following axioms: Bilinearity for all scalars a b in F and all elements x y z in Anticommutativity , or skew-symmetry: for all elements x y in When F is a field of characteristic two, one has to impose the stronger condition for all x in The Jacobi identity for all x y z in For any associative algebra A with multiplication *, one can construct a Lie algebra
