Abstract

We give an introduction to the Z\mathbb{Z}-graded representation theory of the BGG category O\mathcal{O} of a complex semisimple Lie algebras, with an emphasis on Soergel's combinatorial V\mathbb{V} functor, definitions of Z\mathbb{Z}-graded duality functors and definitions of Z\mathbb{Z}-graded translation functors.
