Abstract | We study self-dual representations of a quiver. These differ from ordinary representations by having classical groups, instead of general linear groups, as symmetries. We compute counting functions for the stack of semistable self-dual representations and describe their wall-crossing under changes in stability. The observed behaviour is consistent with formulas appearing in the physics literature on BPS state counting in the presence of an orientifold. Our primary tool is a representation of the Hall algebra which is a mathematical model for the space of BPS states in an orientifold theory. |
