(Mn-43), Volume 43","description":"\u003cp\u003eAddressing physicists and mathematicians alike, this book discusses the finite dimensional representation theory of \u003ci\u003esl(2), \u003c\/i\u003e both classical and quantum. Covering representations of \u003ci\u003eU(sl(2)), \u003c\/i\u003e quantum \u003ci\u003esl(2), \u003c\/i\u003e the quantum trace and color representations, and the Turaev-Viro invariant, this work is useful to graduate students and professionals. \u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e The classic subject of representations of \u003ci\u003eU(sl(2))\u003c\/i\u003e is equivalent to the physicists' theory of quantum angular momentum. This material is developed in an elementary way using spin-networks and the Temperley-Lieb algebra to organize computations that have posed difficulties in earlier treatments of the subject. The emphasis is on the 6\u003ci\u003ej\u003c\/i\u003e-symbols and the identities among them, especially the Biedenharn-Elliott and orthogonality identities. The chapter on the quantum group \u003ci\u003eUb-3.0 qb0(sl(2))\u003c\/i\u003e develops the representation theory in strict analogy with the classical case, wherein the authors interpret the Kauffman bracket and the associated quantum spin-networks algebraically. The authors then explore instances where the quantum parameter \u003ci\u003eq\u003c\/i\u003e is a root of unity, which calls for a representation theory of a decidedly different flavor. The theory in this case is developed, modulo the trace zero representations, in order to arrive at a finite theory suitable for topological applications. The Turaev-Viro invariant for 3-manifolds is defined combinatorially using the theory developed in the preceding chapters. Since the background from the classical, quantum, and quantum root of unity cases has been explained thoroughly, the definition of this invariant is completely contained and justified within the text.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e J.
