[Geom., Alg. & Phys.] An introduction to sl(3) web categorification
ABSTRACT
We explain how to construct a category with objects---Kuperberg sl(3) webs with a given boundary. Morphisms are foam cobordisms between them modulo suitable relations. The Karoubi envelope categorifies the space of quantum sl(3) invariants of tensor products of the fundamental and dual fundamental representations.
