量子图谱隙的尖直径界

Sharp diameter bound on the spectral gap for quantum graphs

David Borthwick, Livia Corsi, Kenny Jones

摘要:

我们建立了紧致量子图的谱隙的一个上界,它只依赖于图的直径和顶点总数。对于边数趋于无穷大的南瓜链,这个界是渐近尖锐的。

英文摘要:

We establish an upper bound on the spectral gap for compact quantum graphs which depends only on the diameter and total number of vertices. This bound is asymptotically sharp for pumpkin chains with number of edges tending to infinity.
