Moduli Spaces of Instantons in Flag Manifold Sigma Models -- Vortices in Quiver Gauge Theories

Toshiaki Fujimori, Muneto Nitta, Keisuke Ohashi

In this paper, we discuss lumps (sigma model instantons) in flag manifold sigma models. In particular, we focus on the moduli space of BPS lumps in general Kähler flag manifold sig…
