Maths HEP Lunchtime Seminars: Noncentral extension of AdS superalgebra
22 October 2004 00:00 in CM221
"Four dimensional N=4 super Yang-Mills theory contains a bigger superalgebra structure than AdS or superconformal algebra, su(2,2|4). It corresponds to a noncentral extension of the latter. The talk is based on hep-th/0404051, and aimed both for the physicsts as well as mathematicans interested in a novel way of obtaining noncentral extensions of Lie algebras."
