The Decay and Fission algorithm for good quivers
Let be a good 3d quiver theory, let denote its Coulomb branch, and let be the set of decay and fission products of , ordered by . The Decay and Fission algorithm. There exists a 1-to-1 correspondence between the poset of symplectic leaves of and the poset . This conjectural correspondence would give a combinatorial construction of the Hasse diagram of the Coulomb branch. Its general validity is presented as conjectural in the source.
