On Euler's abelian relation of the web induced by the forgetful maps on the moduli space ${\mathcal{M}}_{0,\mathbf{n}+3}$: the case when $n$ is even

Luc Pirio

In a previous paper $[P1]$, for every $n\ge 2$, we studied the curvilinear web ${\mathcal{W}}_{0,n+3}$ on the moduli space ${\mathcal{M}}_{0,n+3}$, defin…
