In mathematics, a uniform matroid is a matroid in which the independent sets are exactly the sets containing at most r elements, for some fixed integer r. An alternative definition is that every permutation of the elements is a symmetry. (Wikipedia).

Joseph Bonin: Delta-matroids as subsystems of sequences of Higgs lifts
Abstract: Delta-matroids generalize matroids. In a delta-matroid, the counterparts of bases, which are called feasible sets, can have different sizes, but they satisfy a similar exchange property in which symmetric differences replace set differences. One way to get a delta-matroid is to t

Whitney numbers via measure concentration in representation varieties - Karim Adiprasito
Karim Adiprasito Member, School of Mathematics March 3, 2015 We provide a simple proof of the Rota--Heron--Welsh conjecture for matroids realizable as c-arrangements in the sense of Goresky--MacPherson: we prove that the coefficients of the characteristic polynomial of the associated matr

Yuval Filmus: Monotone Submodular Optimization over a Matroid
We consider the NP-hard problem of maximizing a monotone submodular function over a matroid constraint. Vondrak's continuous greedy algorithm achieves the best possible approximation ratio 1-1/e using continuous methods. Can the same be accomplished combinatorially? We show that this is ar

Abstract: The classical Tverberg's theorem says that a set with sufficiently many points in R^d can always be partitioned into m parts so that the (m - 1)-simplex is the (nerve) intersection pattern of the convex hulls of the parts. Our main results demonstrate that Tverberg's theorem is b
