Graph Design for One Graph(II)
摘要/Abstract
摘要:
图H是带3条弦及1条悬边的5长圈,其λ=1时的图设计结论已知.现运用"差方法"、"带洞图设计"等工具,结合一系列小设计的构作,研究λ>1的情况下HGDλ(v)的存在性,并完成其存在谱:HGDλ(v)存在 λv(v-1)≡0(mod18)且(v,λ)≠(9,1).
Abstract:
The existence result of H-GD(v) was obtained where H is a 5-circuit with three chords and one suspended edge.Continue the research for the existence of H-GD_λ(v),λ1,and complete its existence spectrum:H-GD_λ(v) exists if and only if λv(v-1)≡0*!(mod*!18) and (v,λ)≠(9,1).
