Abstract: A bstractWe explore the physics of two-body decay of BPS states using semiclassical analysis to construct explicit solutions that illustrate the main features of wall crossing, for both ordinary and framed BPS states. In particular… read more here.

Abstract: Abstract We study the BPS spectrum of four-dimensional $$ \mathcal{N} $$ N = 2 supersymmetric Yang-Mills theory with gauge group SU(2) and a massive adjoint hypermultiplet, which has an extremely intricate structure with infinite spectrum… read more here.

Abstract: In this paper, we prove a wall-crossing formula for $\epsilon$-stable quasimaps to GIT quotients conjectured by Ciocan-Fontanine and Kim, for all targets in all genera, including the orbifold case. We prove that adjacent chambers give… read more here.

DOI: 10.1007/s10711-018-0341-6
Abstract: Holomorphic chains on a Riemann surface arise naturally as fixed points of the natural $$\mathbb {C}^*$$C∗-action on the moduli space of Higgs bundles. In this paper we associate a new quiver bundle to the $${{\mathrm{Hom}}}$$Hom-complex… read more here.
