DESCRIPTION:Speaker: Marcus Sperling\nhosted by Tamas Hausel\nAbstract: In 
 three-dimensional N=4 supersymmetric gauge theories defined by quivers\, o
 ne can associate two hyper-Khler moduli spaces: the Higgs and Coulomb bran
 ches. While the Higgs branch has been well-understood for decades\, both m
 athematically via the hyper-Khler quotient and physically through classica
 l field theory\, the Coulomb branch presents deeper challenges. Quantum ef
 fects obscure the classical picture\, and a mathematically rigorous defini
 tion has only emerged in the past decade. In this talk\, I focus on the Co
 ulomb branches of quiver gauge theories and introduce a physics-inspired s
 trategy based on "decay and fission" of quivers.
