As an exercise, convince yourself of the following: Let and denote the reections in two of the axes of symmetry of an equilateral triangle. Section 2 introduces an algebraic notation for recording symmetries and calculating composites and inverses of symmetries. Multiplying from the left by x-1 i we obtain x j= x k, which contradicts our assumption that x jand x kare distinct . Fact. Group Theory and Q.M. There are many examples of groups which are not abelian. The smallest of these is the group of symmetries of an equilateral triangle.

It arises in puzzles, visual arts, music, nature, the physical and life sciences, computer science, cryptography, and of course, all throughout mathematics. Perturbation Theory; Outline for Qualitative MO Lectures. This theory appears all over the place, even before its origin in 1896: In its origin, group theory appears as symmetries. If Gis a p-group, then 1 6= Z(G) G. Hence Gis not simple. Associativity - that is, for any x;y;z2G, we have (xy) z= x(yz). If ; 2Sym(X), then the image of xunder the composition is x = (x ) .) Geometric group theory Lecture Notes M. Hull 1 Introduction One of the main themes of geometric group theory is to study a ( nitely generated) group Gin terms of the geometric properties of the Cayley graph of G.
