随机拉丁方图

Random Latin square graphs

Demetres Christofides, Klas Markström

摘要:

在本文中,我们介绍了新的模型的随机图,所产生的拉丁方,其中包括随机凯莱图作为一种特殊情况。我们研究了这类图的团、独立性、色数、扩张性、连通性和Hamilton性等性质。所得结果与其他随机图模型进行了比较,并指出了一些异同。对于许多性质,我们的结果一般情况下是强大的随机凯莱图的已知结果,有时提高以前最好的结果凯莱情况。

英文摘要:

In this paper we introduce new models of random graphs, arising from Latin squares which include random Cayley graphs as a special case. We investigate some properties of these graphs including their clique, independence and chromatic numbers, their expansion properties as well as their connectivity and Hamiltonicity. The results obtained are compared with other models of random graphs and several similarities and differences are pointed out. For many properties our results for the general case are as strong as the known results for random Cayley graphs and sometimes improve the previously best results for the Cayley case.
