One of the goals of the categorification program is to construct a homological invariant of $3$-manifolds coming from the higher representation theory of quantum groups. The WRT $3$-manifold invariant uses quantum groups at a root of unity.
$p$-DG theory was introduced by Khovanov as a means to categorify objects at prime roots of unity. We will review this machinery and show how to construct categorifications of certain representations of quantum $\mathfrak{sl} (2)$ at prime roots of unity.
