Quiver matroids -- Matroid morphisms, quiver Grassmannians, their Euler characteristics and -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…

Two comparison theorems for semiring schemes
Oliver Lorscheid
In this note, we compare the two approaches to semiring schemes as topological spaces with a structure sheaf and as a functor of points. We explain and prove the following two resu…

Toolkit for the algebraic geometer
Sourayan Banerjee, Oliver Lorscheid, Alejandro MartÃnez Méndez +1
In this text, we outline a theory of schemes associated with a site, which generalizes a variety of geometries, such as manifolds, schemes, analytic spaces, simplicial complexes, a…
