Tree metrics and log-concavity for matroids
Federico Ardila-Mantilla, Sergio Cristancho, Graham Denham +3
We show that a set function satisfies the gross substitutes property if and only if its homogeneous generating polynomial is a Lorentzian polynomial for all positive…
Cleanliness and the Varchenko-Gelfand algebra
Graham Denham, Galen Dorpalen-Barry, Nicholas Proudfoot
A central question in the theory of hyperplane arrangements is when the complement of a complex arrangement is aspherical. Barkley and Speyer introduced a class of real arrangement…
A Leray model for the Orlik-Solomon algebra
Christin Bibby, Graham Denham, Eva Maria Feichtner
We construct a combinatorial generalization of the Leray models for hyperplane arrangement complements. Given a matroid and some combinatorial blowup data, we give a presentation f…
