A Forbidden-Minor Characterization for the Class of graphic Matroids which yield the Co-graphic Element-Splitting Matroids

S. B. Dhotre, P. P. Malavadkar

摘要:

对图拟阵的元素分裂操作一般不产生余图拟阵。本文给出了图拟阵在元素分裂下产生上图拟阵的一个充要条件。

英文摘要:

The element splitting operation on a graphic matroid, in general may not yield a cographic matroid. In this paper, we give a necessary and sufficient condition for the graphic matroid to yield cographic matroid under the element splitting operation.
