Quiver Hecke categorification conjecture for K-theoretic Coulomb branches
Quiver Hecke categorification conjecture for K-theoretic Coulomb branches
Let be an ADE root system, let be an orientation of its Dynkin diagram, and let be a positive root. Set and . Let be the specified monoidal subcategory of finite-dimensional graded modules over the quiver Hecke algebra of affine type , and let be the corresponding localized canonical-basis category. Quiver Hecke categorification conjecture. There is a monoidal functor
which takes distinct simples to distinct simples. In particular, the bases defined by the classes of simples in each category coincide, up to inverting certain classes of simples in . This is proposed for quiver gauge theories whose Coulomb branches are related to open Richardson varieties and quiver Hecke algebra module categories; the source gives no resolution.
