Abstract

We equip Ellis and Brundan’s version of the odd categorified quantum group for with a differential giving it the structure of a graded dg-2-supercategory. The presence of the super grading gives rise to two possible decategorifications of the associated dg-2-category. One version gives rise to a categorification of quantum at a fourth root of unity, while the other version produces a subalgebra of quantum defined over the integers. Both of these algebras appear in connection with quantum algebraic approaches to the Alexander polynomial.
