  • 简介:枚举盖住设计的图的几种类型的同晶型班是在计算的拓扑的图理论的中央研究话题之一。如果它的盖住的图是circulant,G盖住的A被称为circulant。最近,作者[分离数学,277,73鈥?5(2004)]枚举circulant的同晶型班某个类型的两倍覆盖物,叫了典型盖住,并且证明两倍原子价三的一张circulant图盖住都不是circulant。另外,在里面[图和组合数学,21,386鈥?00(2005)],circulant的同晶型班加倍原子价的一张circulant图的覆盖物四被枚举。在这篇论文,circulant的同晶型班加倍原子价的一张circulant图的覆盖物五被枚举。盖住的关键词图-电压赋值-Cayley-circulant图先生(2000)题目分类05C10-第一写作的05C30被中国(号码60473019和10571005)的NSF并且由NKBRPC(2004CB318000)支持,并且第二个作者被Com2MaC鈥揔OSEF在朝鲜支持

  • 简介:加倍是与高分辨率构造二水平的部分因素的图案的一个简单却强大的方法。这篇文章以两倍图案的李差异学习一致性。我们在不同标准下面给在两倍设计的一致性和原来的错误盒子之间的一些连接。而且,在两倍设计和原来的的概括wordlength模式之间的一些分析连接第一这里被提供,它扩大存在调查结果。为两倍图案的李差异的更低的界限也被给。
