2-边连通3-正则非上可嵌入图的扩充

It is known(5) that an investigation of the up-embeddability of the 3-regular graphs shows a useful approach to that of the general graph. But as far, very few characterizations of the up-embeddability are known on the 3-regular graphs. LetG be a 2-edge connected 3-regular graph. We prove thatG is u... View More
