Forward to matroids The Top Heavy Conjecture makes sense for arbitrary matroids! Any matroid has a lattice of ats L(M) with a rank function. Conjecture (Dowling{Wilson 1974)

WebNov 10, 2024 · This is relevant to a conjecture of Topping. ... the Heron-Rota-Welsh conjecture about the log-concavity of the coefficients of chromatic polynomials and the Top-heavy conjecture by Dowling-Wilson on the number of subspaces spanned by a finite set of vectors in a vector space. I will explain how topological and algebra-geometric … In 2009, during his PhD studies, Huh proved Read's conjecture about the unimodality of the coefficients of chromatic polynomials in the context of graph theory, which had been unresolved for more than 40 years. In joint work with Karim Adiprasito and Eric Katz, he resolved the Heron–Rota–Welsh conjecture on the log-concavity of the characteristic polynomial of matroids. With Karim Adiprasito, he is one of five winners of the 2024 New Horizons Prize for Early-Caree… city of topeka trash
