A base exchange property for regular matroids
In this paper, we show that for any two bases B and B of a regular matroid, there is an element e ∈ B such that there is a unique element f ∈ B for which both (B\{e}) ∪ {f} and (B\{f}) ∪ {e} are bases of M. This solves a problem posed by White in 1980.
متن کاملGENERALIZED ∆ − Y EXCHANGE AND k – REGULAR MATROIDS
This paper introduces a generalization of the matroid operation of ∆ − Y exchange. This new operation, segment-cosegment exchange, replaces a coindependent set of k collinear points in a matroid by an independent set of k points that are collinear in the dual of the resulting matroid. The main theorem of the first half of the paper is that, for every field, or indeed partial field, F, the class...
متن کاملBase exchange properties of graphic matroids
New base exchange properties of binary and graphic matroids are derived. The graphic matroids within the class of 4-connected binary matroids are characterized by base exchange properties. Some progress with the characterization of arbitrary graphic matroids is made. Characterizing various types of matroids by base exchange properties is e.g. important in invariant theory.
متن کاملFamilies of Regular Matroids
This is an introductory paper about the category of regular oriented matroids (ROMs). We compare the homotopy types of the categories of regular and binary matroids. For example, in the unoriented case, they have the same fundamental group but we show that the higher homotopy groups are different for rank three regular and binary matroids. We also speculate on the possible impact of a recent th...
متن کاملk-Regular Matroids
The class of matroids representable over all fields is the class of regular matroids. The class of matroids representable over all fields except perhaps GF (2) is the class of near-regular matroids. Let k be a non-negative integer. This thesis considers the class of k–regular matroids, a generalization of the last two classes. Indeed, the classes of regular and near-regular matroids coincide wi...
