Charges and homologies in AdS_4/CFT_3
arXiv:0903.3095
Abstract
Electric and magnetic charges of a certain class of operators in N=2 large N quiver Chern-Simons theories are investigated. We consider only non-chiral theories, in which every bi-fundamental field appears with its conjugate representation. By interpreting operators in a Chern-Simons theory as wrapped M-branes in the dual geometry AdS_4 x X_7, we partly determine the homologies of X_7.
