Log-Concavity of the Grothendieck Classes of Banana Graphs and Clasped Necklaces

Stephanie Chen

The Grothendieck classes of melonic graphs satisfy a recursive relation and may be written as polynomials in the class of the moduli space $M_{0, 4}$ with nonnegative inte…

Log concavity of the Grothendieck class of $M_{0, n}$

Paolo Aluffi, Stephanie Chen, Matilde Marcolli

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