Cohomology of moduli spaces of pointed curves

Jinwon Choi, Young-Hoon Kiem

In this paper, after reviewing recent progress on the cohomology of $M_{0, n}$ , we further our investigation on the cohomology of moduli spaces of pointed curves in…

Asymptotic distribution of the Betti numbers of $M_{0, n}$

Jinwon Choi, Young-Hoon Kiem

Asymptotic normality is frequently observed in large combinatorial structures, rigorously established for many quantities such as cycles or inversions in random permutations, the n…

Characteristic polynomial of $M_{0, n}$ and log-concavity

Jinwon Choi, Young-Hoon Kiem, Donggun Lee

Motivated by Stanley's generalization of the chromatic polynomial of a graph to the chromatic symmetric function, we introduce the characteristic polynomial of a representation of…

Recursive algorithm and log-concavity of representations on the cohomology of $M_{0, n}$

Jinwon Choi, Young-Hoon Kiem, Donggun Lee

We provide a programmable recursive algorithm for the $S_{n}$ -representations on the cohomology of the moduli spaces $M_{0, n}$ of $n$ -pointed stable curv…
