Abstract

We give an excluded-minor characterization for the class of matroids M in which M {set minus} e or M / e is binary for all e in E (M) This class is closely related to the class of matroids in which every member is binary or can be obtained from a binary matroid by relaxing a circuit-hyperplane. We also provide an excluded-minor characterization for the second class. © 2013 Elsevier Ltd.
