Duality and Braiding in Twisted Quantum Field Theory
Mauro Riccardi, Richard J. Szabo
We re-examine various issues surrounding the definition of twisted quantum field theories on flat noncommutative spaces. We propose an interpretation based on nonlocal commutative…
D-branes, KK-theory and duality on noncommutative spaces
J. Brodzki, V. Mathai, J. Rosenberg +1
We present a new categorical classification framework for D-brane charges on noncommutative manifolds using methods of bivariant K-theory. We describe several applications includin…
Nonabelian localization for gauge theory on the fuzzy sphere
Harold Steinacker, Richard J. Szabo
We apply nonabelian equivariant localization techniques to Yang-Mills theory on the fuzzy sphere to write the partition function entirely as a sum over local contributions from cri…
DLCQ Strings, Twist Fields and One-Loop Correlators on a Permutation Orbifold
Henry C. D. Cove, Zoltan Kadar, Richard J. Szabo
We investigate some aspects of the relationship between matrix string theory and light-cone string field theory by analysing the correspondence between the two-loop thermal partiti…
Quiver Gauge Theory and Noncommutative Vortices
Olaf Lechtenfeld, Alexander D. Popov, Richard J. Szabo
We construct explicit BPS and non-BPS solutions of the Yang-Mills equations on noncommutative spaces R^{2n}_theta x G/H which are manifestly G-symmetric. Given a G-representation,…
Worldsheet Instantons and a Null String Limit of Born-Infeld Theory
Gerald A. Goldin, Nick E. Mavromatos, Richard J. Szabo
For a superstring theory in four spacetime dimensions, we propose a modification of the Born-Infeld action that possesses a well-defined tensionless limit. We interpret this as des…
