Doing so, we answer questions first introduced in doi.org/10.1016/j.ce... through a systematic exploration of sign patterns in the associated oriented matroids. The Maple implemtation of this algorithm is available at git.mpi-cbg.de/scholten/fea...

We prove certain 4-species ecological networks cannot achieve stable coexistence, no matter the parameters. The proof uses combinatorial insights from oriented matroid theory to study feasibility/stability constraints algorithmically 🔍

How do you know if species can coexist? The feasible-stable equilibria of Lotka-Volterra systems form semialgebraic sets in parameter space. We recast this using Plücker coordinates & the Grassmannian - opening new computational approaches to ecological networks.

New preprint: We study Lotka-Volterra ecological dynamics through computational algebraic geometry. By encoding feasibility & stability on the real Grassmannian, we prove certain ecological networks are mathematically impossible 🧮🌿 arxiv.org/abs/2509.00165
