Conformal perturbation theory beyond the leading order
Matthias R. Gaberdiel, Anatoly Konechny, Cornelius Schmidt-Colinet
Higher order conformal perturbation theory is studied for theories with and without boundaries. We identify systematically the universal quantities in the beta function equations,…
Duality covariant quantum field theory on noncommutative Minkowski space
Andre Fischer, Richard J. Szabo
We prove that a scalar quantum field theory defined on noncommutative Minkowski spacetime with noncommuting momentum coordinates is covariant with respect to the UV/IR duality whic…
SU(3)-Equivariant Quiver Gauge Theories and Nonabelian Vortices
Olaf Lechtenfeld, Alexander D. Popov, Richard J. Szabo
We consider SU(3)-equivariant dimensional reduction of Yang-Mills theory on Kaehler manifolds of the form M x SU(3)/H, with H = SU(2) x U(1) or H = U(1) x U(1). The induced rank tw…
Instantons and Donaldson-Thomas Invariants
Michele Cirafici, Annamaria Sinkovics, Richard J. Szabo
We review some recent progress in understanding the relation between a six dimensional topological Yang-Mills theory and the enumerative geometry of Calabi-Yau threefolds. The gaug…
Magnetic Charge Lattices, Moduli Spaces and Fusion Rules
L. Kampmeijer, J. K. Slingerland, B. J. Schroers +1
We analyze the set of magnetic charges carried by smooth BPS monopoles in Yang-Mills-Higgs theory with arbitrary gauge group G spontaneously broken to a subgroup H. The charges are…
Cohomological gauge theory, quiver matrix models and Donaldson-Thomas theory
Michele Cirafici, Annamaria Sinkovics, Richard J. Szabo
We study the relation between Donaldson-Thomas theory of Calabi-Yau threefolds and a six-dimensional topological Yang-Mills theory. Our main example is the topological U(N) gauge t…
