Decay and fission of magnetic quivers

Abstract: Over the past 5 years, the stratification of 3d Coulomb branches into symplectic leaves has been the subject of intense work in the physics community. Mathematically, this corresponds to understanding the nested singularity structure of conical symplectic singularities. This class includes Nakajima quiver varieties, slices in affine grassmannians, instanton moduli spaces, and much more. In this talk, I will review the methods that have been developed, centered on the concept of magnetic quivers. I will show how insights from string theory provide easy algorithms that can be implemented on a computer.
