On Excluded Minors for Even Cut Matroids
Pivotto, Irene (University of Waterloo, 2007-01-22)In this thesis we will present two main theorems that can be used to study minor minimal non even cut matroids. Given any signed graph we can associate an even cut matroid. However, given an even cut matroid, there are ...
