论文摘要
我们表征了双圆形和共圆形矩阵的交点的三个相互连接的成员。除了一些具有排名和Corank的杰出矩形外，该课程仅包括免费的漩涡及其未成年人。
We characterize the 3-connected members of the intersection of the class of bicircular and cobicircular matroids. Aside from some exceptional matroids with rank and corank at most 5, this class consists of just the free swirls and their minors.
