Topological Solitons Seminar: Sasakian Quiver Gauge Theories and Instantons
4 November 2015 13:00 in CM221
We consider SU(3)-equivariant dimensional reduction of Yang–Mills theory over certain cyclic orbifolds of the 5-sphere which are Sasaki–Einstein manifolds. We obtain new quiver gauge theories for which we describe the Higgs branches as moduli spaces of spherically symmetric instantons which are SU(3) -equivariant solutions to the Hermitian Yang–Mills equations on the associated Calabi–Yau cones. Moreover, we compare these spaces to moduli spaces of translationally-invariant instantons on the cones. We provide an explicit unified construction of these moduli spaces as Kähler quotients.
