我们研究了Goel,Montenegro和Tetali在可逆条件下连续时间随机游动的L1混合时间的谱Prole界。我们发现,它是精确的对数对数因子,这个对数对数因子不能提高。
We examine the spectral prole bound of Goel, Montenegro and Tetali for the L 1 mixing time of continuous-time random walk in reversible settings. We nd that it is precise up to a log log factor, and that this log log factor cannot be improved.
