电流的定位

Localization of Electrical Flows

Aaron Schild, Satish Rao, Nikhil Srivastava

摘要:

我们表明,在任何图中,在一个随机边缘的端点之间的电流的流路的平均长度是$O(\log^2 n)$。这是一个更一般的结果的结果,该结果表明图的传递阻抗矩阵的入口方向绝对值的谱范数是$O(\log^2 n)$。这一结果意味着一个简单的不经意的路由方案的基础上,在可传递图的情况下的电流。

英文摘要:

We show that in any graph, the average length of a flow path in an electrical flow between the endpoints of a random edge is $O(\log^2 n)$. This is a consequence of a more general result which shows that the spectral norm of the entrywise absolute value of the transfer impedance matrix of a graph is $O(\log^2 n)$. This result implies a simple oblivious routing scheme based on electrical flows in the case of transitive graphs.
