Web7 Symmetry and Group Theory One of the most important and beautiful themes unifying many areas of modern mathematics is the study of symmetry. Many of us have an intuitive idea of symmetry, and we often think about certain shapes or patterns as being more or less symmetric than others. A square is in some sense “more symmetric” than Webwhich is a statement about the orthogonality between the matrix ele-ments corresponding to diﬁerent irreducible representations of a group. For many applications of group theory, however, the full matrix rep-resentations of a group are not required, but only the traces within classes of group elements called \characters." A typical application

WebBasic Problem of Representation Theory: Classify all representations of a given group G, up to isomorphism. For arbitrary G, this is very hard! We shall concentrate on ﬁnite groups, where a very good general theory exists. Later on, we shall study some examples of topological compact groups, such as U(1) and SU(2).
