| Title: | Disconnected forms of the standard group | Authors: | McInnes, B. | Issue Date: | Aug-1997 | Citation: | McInnes, B. (1997-08). Disconnected forms of the standard group. Journal of Mathematical Physics 38 (8) : 4354-4362. ScholarBank@NUS Repository. | Abstract: | Recent work in quantum gravity has led to a revival of interest in the concept of disconnected gauge groups. Here we explain how to classify all of the (nontrivial) groups which have the same Lie algebra as the "standard group," SU(3)×SU(2)×U(1), without requiring connectedness. The number of possibilities is surprisingly large. We also discuss the geometry of the "Kiskis effect," the ambiguity induced by nontrivial space-time topology in such gauge theories. © 1997 American Institute of Physics. | Source Title: | Journal of Mathematical Physics | URI: | http://scholarbank.nus.edu.sg/handle/10635/103135 | ISSN: | 00222488 |
