Koszulness and supersolvability for Dirichlet arrangements

Bob Lutz

We prove that the cone over a Dirichlet arrangement is supersolvable if and only if its Orlik-Solomon algebra is Koszul. This was previously shown for four other classes of arrange…

Matroids arising from electrical networks

Bob Lutz

This paper introduces Dirichlet matroids, a generalization of graphic matroids arising from electrical networks. We present four main theorems. First, we exhibit a matroid quotient…
