Cross‐ratio degrees and triangulations
R Silversmith - Bulletin of the London Mathematical Society, 2024 - Wiley Online Library
The cross‐ratio degree problem counts configurations of nn points on P 1 P^1 with n− 3 n-3
prescribed cross‐ratios. Cross‐ratio degrees arise in many corners of combinatorics and …

Stable curves and chromatic polynomials
B Reinke, R Silversmith - arXiv preprint arXiv:2411.17551, 2024 - arxiv.org
The intersection numbers of moduli spaces of stable curves $\overline {\mathcal {M}} _ {g, m}
$ are well-studied and are known to have rich combinatorial structure. We introduce a …
