Query: Categorification of Verma modules and indecomposable projective modules
  in the category $\mathcal I_{\mathfrak{g}}(\mathfrak{sl}_2)$ for
  $\mathfrak{sl}_2$   We categorify Verma and indecomposable projective modules in the category
$\mathcal I_{\mathfrak{g}}(\mathfrak{sl}_2)$ for $\mathfrak{sl}_2$ using a
tensor product decomposition theorem of T. J. Enright and work of J. Chuang and
R. Rouquier, A. Licata and A. Savage (Hecke algebras, finite general linear
groups, and Heisenberg categorification) and M. Khovanov (Heisenberg algebra
and a graphical calculus).
