D-branes and bivariant K-theory
Richard J. Szabo
We review various aspects of the topological classification of D-brane charges in K-theory, focusing on techniques from geometric K-homology and Kasparov's KK-theory. The latter fo…
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…
