Abstract

Abstract: It follows from the work of Burban and Drozd [ Math. Ann . 351 (2011) 665–709] that for nodal curves C, the derived category of modules over the Auslander order A C provides a categorical (smooth and proper) resolution of the category of perfect complexes Perf ( C ) . On the A‐side, it follows from the work of Haiden–Katzarkov–Kontsevich [ Publ. Math. Inst. Hautes Études Sci . 126 (2017) 247–318] that for punctured surfaces X with stops Λ at their boundary, the partially wrapped Fukaya category W ( X, Λ ) provides a categorical (smooth and proper) resolution of the compact Fukaya category F ( X ) . Inspired by this analogy, we establish an equivalence between the derived category of modules over the Auslander orders over certain nodal stacky curves and partially wrapped Fukaya categories associated to punctured surfaces of arbitrary genus equipped with stops at their boundary. As an application, we deduce equivalences between derived categories of coherent sheaves (respectively perfect complexes) on such nodal stacky curves and the wrapped (respectively compact) Fukaya categories of punctured surfaces of arbitrary genus.
