三次图的同构双射

Isomorphic Bisections of Cubic Graphs

Shagnik Das, Alexey Pokrovskiy, Benny Sudakov

摘要:

图划分,或者根据某些条件将图划分为两个或更多部分,在离散数学中自然出现,并且此类问题已被广泛研究。在20世纪90年代,Ando证明了每一个三次图的顶点都可以划分为两部分,从而导出同构子图。利用概率方法和细致的推理论证,我们证明了大连通图的Ando猜想。

英文摘要:

Graph partitioning, or the dividing of a graph into two or more parts based on certain conditions, arises naturally throughout discrete mathematics, and problems of this kind have been studied extensively. In the 1990s, Ando conjectured that the vertices of every cubic graph can be partitioned into two parts that induce isomorphic subgraphs. Using probabilistic methods together with delicate recolouring arguments, we prove Ando's conjecture for large connected graphs.
