Quiver matroids -- Matroid morphisms, quiver Grassmannians, their Euler characteristics and $F_{1}$ -points

Manoel Jarra, Oliver Lorscheid, Eduardo Vital

In this paper, we introduce morphisms for matroids with coefficients (in the sense of Baker and Bowler) and quiver matroids. We investigate their basic properties, such as functori…
