10 Mar 2003 | Journal: | manuscripta math., 114, 531-547 (2004) | Subject: | Quantum Algebra MSC-class: 22E46;22E67;81R10 | math.QA hep-th | Abstract: | We show that untwisted respectively twisted conjugacy classes of a compact and simply connected Lie group which satisfy a certain integrality condition correspond naturally to irreducible highest weight representations of the corresponding affine Lie algebra. Along the way, review the classification of twisted conjugacy classes of a simply connected compact Lie group $G$ and give a description of their stabilizers in terms of the Dynkin diagram of the corresponding twisted affine Lie algebra. | Source: | arXiv, math.QA/0303118 | Services: | Forum | Review | PDF | Favorites |
