We consider a possible framework to categorify the exponential map exp(− f) given the categorification of a generator f of sl 2 by Lauda. In this setup the Taylor expansions of exp(− f) and exp(f) turn into complexes built out of categorified divided powers of f. Hom spaces between tensor powers of categorified f are given by diagrammatics combining nilHecke algebra relations with those for a additional “short strand” generator. The proposed framework is only an approximation to categorification of exponentiation, because the functors categorifying exp(f) and exp(− f) are not invertible.
