拟阵基对图的性质

Some Properties on Basis Pair Graphs of Matroids

利用拟阵基公理，证明了恒等自对偶拟阵的基对图是连通的，并研究了基对图的邻域结构和自同构群．

The basis pair graphs of self dual matroids are connected by the exchange axiom for bases of matroids,and study the neighbourhood construction and the automorphism group of basis pair graphs of matroids.
