| Abstract: | 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. |
