h(G,x)表示图G的伴随多项式,β(G)表示h(G,x)的最小负实根.证明了当t≥3时,r(1,1,t+1,t,1)和T(1,1,t+2,t,1)的补图的色唯一性。
In this paper,let h(G,x) denote adjoining polynomial of graph G,and β( G ) denote the minimum negative real roots of h( G, x),we prove that ^—T(1,1, t + 1, t ,1) and ^—T(1,1, t + 2, t ,1) with t ≥3 are chromatically unique.
