精确3边连通图的综合

A synthesis for exactly 3-edge-connected graphs

Carl Kingsford, Guillaume Marçais

摘要:

一个多重图是精确k-边连通的,如果任意一对顶点之间恰好有k条边不相交的路。本文刻画了一类3-边连通图,给出了一个包含两个运算的合成,通过这个合成可以生成所有的3-边连通重图。稍加修改的综合给出了平面的精确3-边连通图和具有最少可能边的精确3-边连通图。

英文摘要:

A multigraph is exactly k-edge-connected if there are exactly k edge-disjoint paths between any pair of vertices. We characterize the class of exactly 3-edge-connected graphs, giving a synthesis involving two operations by which every exactly 3-edge-connected multigraph can be generated. Slightly modified syntheses give the planar exactly 3-edge-connected graphs and the exactly 3-edge-connected graphs with the fewest possible edges.
