Non-Binary Matroids Having At Most Three Non-Binary Elements
Published online by Cambridge University Press: 12 September 2008
Abstract
An element e of a matroid M is called non-binary when M\e and M/e are both non-binary matroids. Oxley in [5] gave a characterization of the 3-connected non-binary matroids without non-binary elements. In this paper, we will construct all the 3-connected matroids having 1, 2 or 3 non-binary elements.
