A diagrammatic approach to categorification of quantum groups I

Quantum Algebra 2025-01-23 v2 Representation Theory

Abstract

To each graph without loops and multiple edges we assign a family of rings. Categories of projective modules over these rings categorify Uq(g)U^-_q(\mathfrak{g}), where g\mathfrak{g} is the Kac-Moody Lie algebra associated with the graph.
