Computation of the first Stiefel-Whitney class for the variety $\overline{{\mathcal{M}}_{0,n}^{\mathbb{R}}}$

N. Ya. Amburg, E. M. Kreines

We compute the class which is Poincare dual to the first Stiefel-Whitney class for the Deligne-Mumford compactification of the moduli space of real algebraic curves of genus 0 with…
