Log concavity of the Grothendieck class of ${\overline{\mathcal{M}}}_{0,n}$

Paolo Aluffi, Stephanie Chen, Matilde Marcolli

Using a known recursive formula for the Grothendieck classes of the moduli spaces ${\overline{\mathcal{M}}}_{0,n}$, we prove that they satisfy an asymptotic form of ultra-log-concavit…
