Abstract: Remarkably the geometry of a singular Calabi-Yau threefold is intricately
related to the moduli space of representations of an associated quiver with relations.
While the relations associated to an arbitrary Calabi-Yau threefold are somewhat
mysterious from a mathematical perspective, they are naturally encoded in what
physicists call a superpotential. Recently Szendroi and Nagao-Nakajima analyzed
fixed points of torus actions on the moduli space of framed A-modules. In this talk
we will relate their work to the physical interpretation given by Chuang and Jafferis
in terms of D0/D2/D6 BPS bound states.
