Eulerian and Bipartite Binary Delta-matroids
文献摘要：
Delta-matroid theory is often thought of as a generalization of topological graph theory.It is well-known that an orientable embedded graph is bipartite if and only if its Petrie dual is orientable.In this paper,we first introduce the concepts of Eulerian and bipartite delta-matroids and then extend the result from embedded graphs to arbitrary binary delta-matroids.The dual of any bipartite embedded graph is Eulerian.We also extend the result from embedded graphs to the class of delta-matroids that arise as twists of binary matroids.Several related results are also obtained.
