摘要
结合 4-边形 2 -因子条件 ,确定了一类点的度在 modulo4下值为 0 ,1的上可嵌入图类 .从而综合已有的结果 。
Combined with the condition of 4-quadrangle 2-factor, this paper gives classes of upper embeddable graphs whose value of degree of each vertex is 0 or 1, respectively, under modulo 4. Based on the known,results we characterize entirely the upper embeddability of such clases of graph s containing a 4-quadrangle 2-factor.
