一个n维的递归交互网络Gn的一个点(边)子集称为Gn的一个h-嵌入点(边)割(如果这样的子集存在的话)
使得删去这个点(边)子集后得到的图是不连通的且每个点都在一个未损坏的h-维子网络Gh中.图Gn的h-嵌入(边)连通度
记为ζh(Gn)(ηh(Gn))
定义为Gn的最小h-嵌入点(边)割的基数.完全对换网络CTn是网络设计中一类重要的Cayley图.在本文中
我们确定了完全对换网络的h-嵌入(边)连通度:ζh(CTn)=h!/2[n(n-1)-h(h-1)]
其中2≤h≤n-2
ηh(CTn)=h!/2[n(n-1)-h(h-1)]
其中2≤h≤n-1.
For an n-dimensional recursive interconnection network Gn
the h-embedded connectivity of Gn
denoted by ζh(Gn)(resp. the h-embedded edge-connectivity of Gn
denoted by ηh(Gn))
is the cardinality of a minimum subset of vertices(resp. edges)
if any
whose deletion disconnects Gn and each vertex of remaining components is contained in an undamaged h-dimensional subnetwork Gh. Complete-transposition graphs CTn are a class of important Cayley graphs in network design. In this paper
we determine ζh andηh for complete-transposition graphs: ζh(CTn) =h!/2[n(n-1)-h(h-1)] for 2 ≤ h ≤ n-2
and ηh(CTn) =h!/2[n(n-1)-h(h-1)] for 2 ≤ h ≤ n-1.
