Matroidal Mixed Eulerian Numbers
Eric Katz, Max Kutler
We make a systematic study of matroidal mixed Eulerian numbers which are certain intersection numbers in the matroid Chow ring generalizing the mixed Eulerian numbers introduced by…

The motivic zeta functions of a matroid
David Jensen, Max Kutler, Jeremy Usatine
We introduce motivic zeta functions for matroids. These zeta functions are defined as sums over the lattice points of Bergman fans, and in the realizable case, they coincide with t…
