比较不同大小的图

Comparing Graphs of Different Sizes

Russell Lyons

摘要:

我们考虑两个概念描述如何一个有限图可能比另一个更大。使用它们,我们证明了几个定理,这样的对比较的生成树的数量,返回概率的随机游动,和独立集的数量,以及其他组合量。我们的方法涉及不等式的决定因素,运营商的功能的痕迹,和熵。

英文摘要:

We consider two notions describing how one finite graph may be larger than another. Using them, we prove several theorems for such pairs that compare the number of spanning trees, the return probabilities of random walks, and the number of independent sets, among other combinatorial quantities. Our methods involve inequalities for determinants, for traces of functions of operators, and for entropy.
