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