On the Betti numbers, Poincaré polynomials, and Euler characteristics of ${\overline{\mathcal{M}}}_{0,n}$

Giordano Cotti

In this paper, we revisit the Poincaré polynomials, Betti numbers, and Euler characteristics of the Deligne-Mumford moduli spaces ${\overline{\mathcal{M}}}_{0,n}$ of stable $n$-pointe…
