Abstract: I will discuss techniques for the computation of correlators in (0,2) Landau-Ginzburg models. After introducing these theories from the point of view of heterotic compactifications, I will describe the associated half-twisted models and their basic algebraic structure. This structure enables direct computation of correlators and suggests a generalization of the Grothendieck residue.
