Gutman, Ivan; Fuji, Zhang On a quasiordering of bipartite graphs. (English) Zbl 0623.05050 Publ. Inst. Math., Nouv. Sér. 40(54), 11-15 (1986). For the family B of bipartite graphs, the authors consider a quasi- ordering of B based on the coefficients of their characteristic polynomials. They then prove three rather technical results about bipartite graphs arising from operations involving bipartite graphs, paths and even length cycles.
