Ribbon Graphs and Mirror Symmetry I

Abstract

Given a ribbon graph $\Gamma$ with some extra structure, we define, using constructible sheaves, a dg category $CPM(\Gamma )$ meant to model the Fukaya category of a Riemann surface in the cell of Teichmüller space described by $\Gamma .$ When $\Gamma$ is appropriately decorated and admits a combinatorial "torus fibration with section," we construct from $\Gamma$ a one-dimensional algebraic stack ${\tilde{X}}_{\Gamma }$ with toric components. We prove that our model is equivalent to $Perf({\tilde{X}}_{\Gamma })$, the dg category of perfect complexes on ${\tilde{X}}_{\Gamma }$.
