Hochschild Cohomology of NC Matrix Factorizations.
R. Bocklandt proved a version of mirror symmetry in which the dual
to a punctured curve is a noncommutative Landau-Ginzburg (LG) model: namely,
the Jacobi algebra of a dimer model, equipped with a canonical potential. We
will review the basic theory of dimer models and existing literature on
matrix factorizations of commutative LG models. Then we will present a
conjectural answer for the Hochschild cohomology of matrix factorizations of
noncommutative LG models in terms of a compactly supported version for
