Recently, Goodman et al. [9,10] have proven two conjectures by GrΓΌnbaum right, showing that any arrangement of pseudolines in the plane can be embedded into a flat projective plane and that there exists a universal topological projective plane in which every arrangement of pseudolines is stretchable

The minimum cut problem is a well-solved special case of submodular function minimization. We show that it is in fact equivalent to minimizing a modular function over a ring family. Onehalf of this equivalence follows from classical work of Rhys and Picard. We give a number of applications to testin
