Basile Coron
Current Position
I am currently a postdoctoral fellow at the Institute of Advanced Study in Princeton, for the special year event organized around June Huh.
In 2023-2024 I was a postdoctoral research assistant at the School of Mathematical Sciences of Queen Mary University of London, under the supervision of Alex Fink. I was also the organizer of the Tropical and Geometric Combinatorics research group at QMUL.
My PhD was supervised by Vladimir Dotsenko in Strasbourg. It was awarded the 2024 thesis prize of the university of Strasbourg.

Research interests
My research area is centered around the study of combinatorial objects such as matroids, via methods of algebraic topology (operadic structures, Koszul duality theory).
Publications
An algebraic interpretation of Eulerian polynomials, derangement polynomials, and beyond, via Gröbner methods (arXiv:2410.14199). I use Gröbner methods to revisit and extend the relationship between the Chow rings of permutohedral varieties, and polynomials associated to the ascent statistics on permutations (Eulerian polynomials, derangement polynomials).
Operadic Kazhdan-Lusztig-Stanley theory (arXiv:2402.09905, to appear in IMRN). I use operadic structures to categorify P-kernels and Kazhdan-Lusztig-Stanley polynomials of geometric lattices.
Supersolvability of built lattices and Koszulness of generalized Chow rings (arXiv:2302.13072, to appear in Compositio Maths). I use the operadic structure on geometric lattices introduced in my previous article to prove Koszulness of generalized Chow rings of supersolvable built lattices.
Matroids, Feynman categories, and Koszul duality (arXiv:2211.12370, to appear in The Duke Mathematical Journal). I introduce a Feynman category over which some combinatorial invariants of matroids form some operads, and I prove a Koszul duality result between those operads. This allows a reinterpretation of the combinatorial Leray models for Orlik-Solomon algebras.
