Enumeration of border-strip decompositions & Weil-Petersson volumes

Abstract: We describe an injection from border-strip decompositions of certain shapes to permutations. This allows us to provide enumeration results, as well as $q$-analogues of enumeration formulas. Finally, we use this injection to prove a connection between the number of border-strip decompositions of the $n\times 2n$ rectangle and the Weil-Petersson volume of the moduli space of an $n$-punctured Riemann sphere.
