Noncentral extension of AdS superalgebra

Regular Seminar Jeong-Hyuck Park (IHES-Paris)

16:00 IC
room H503

Four dimensional N=4 super Yang-Mills theory contains a bigger superalgebra than AdS or superconformal algebra, su(2,2/4). It corresponds to a noncentral extension of the latter. The talk is for both physicsts and mathematicans interested in a novel way of obtaining noncentral extensions of Lie algebras.
