Determinantal random subgraphs

Abstract

We define two natural families of determinantal random subgraphs of a finite connected graph, one supported by acyclic spanning subgraphs (spanning forests) with fixed number of components, the other by connected spanning subgraphs with fixed number of independent cycles. Each family generalizes the uniform spanning tree and the generating functions of these probability measures generalize the classical Kirchhoff and Symanzik polynomials. We emphasize the matroidal nature of this construction, as well as possible generalisations.
