Inequivalent Representations of Bias Matroids
Suppose that q is a prime power exceeding five. For every integer N there exists a 3-connected GF(q)-representable matroid, in particular, a free spike or a free swirl, that has at least N inequivalent GF(q)-representations. In contrast to this, Geelen, Oxley, Vertigan and Whittle have conjectured that, for any integer r > 2, there exists an integer n(q, r) such that if M is a 3-connected GF(q)...
متن کاملCharacterizing matchings as the intersection of matroids
This paper deals with the problem of representing the matching independence system in a graph as the intersection of finitely many matroids. After characterizing the graphs for which the matching independence system is the intersection of two matroids, we study the function lðGÞ, which is the minimum number of matroids that need to be intersected in order to obtain the set of matchings on a gra...
متن کاملBias matroids with unique graphical representations
Given a 3-connected biased graph Ω with three node-disjoint unbalanced circles, at most one of which is a loop, we describe how the bias matroid of Ω is uniquely represented by Ω.
متن کاملCharacterizing graphic matroids by a system of linear equations
Given a rank-r binary matroid we construct a system of O(r) linear equations in O(r) variables that has a solution over GF(2) if and only if the matroid is graphic.
متن کاملCharacterizing binary matroids with no P 9 - minor
3 In this paper, we give a complete characterization of binary matroids 4 with no P9-minor. A 3-connected binary matroid M has no P9-minor 5 if and only if M is one of the internally 4-connected non-regular minors 6 of a special 16-element matroid Y16, a 3-connected regular matroid, a 7 binary spike with rank at least four, or a matroid obtained by 3-summing 8 copies of the Fano matroid to a 3-...
