  We apply the sheaf cohomology BGG method developed by the authors and
Lachowska-Qi to the computation of Hochschild cohomology groups of various
blocks of the small quantum group. All our computations of the center of the
corresponding block agree with the conjectures of Lachowska-Qi. In the case of
the nontrivial singular block for $\mathfrak{g} = \mathfrak{sl}_3$, we obtain
the H*$(\mathfrak{u}, \mathbb{C}) = \mathbb{C}[\mathcal{N}]$-module structure
of HH*$(\mathfrak{u}_{\lambda})$.
