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 Teichm"uller 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 $X_\Gamma$ with toric components. We prove that our model is equivalent to $Perf(X_\Gamma)$, the dg category of perfect complexes on $X_\Gamma$.
