Moduli Spaces of Polygons and Punctured Riemann Spheres
Published online by Cambridge University Press: 20 November 2018
Abstract
The purpose of this note is to give a simple combinatorial construction of the map from the canonically compactified moduli spaces of punctured complex projective lines to the moduli spaces ${{P}_{r}}$ of polygons with fixed side lengths in the Euclidean space ${{\mathbb{E}}^{3}}$. The advantage of this construction is that one can obtain a complete set of linear relations among the cycles that generate homology of ${{P}_{r}}$. We also classify moduli spaces of pentagons.
