摘要

我们考虑了时间和边长同时趋于零的情况下等边图上离散热核的渐近线。根据时间和边长之间的渐近比，我们证明会出现两种不同的状态：(i) 高斯状态和 (ii) 泊松状态，它们分别类似于热核在 (i) 欧几里得空间和 (ii) 图上的短时渐近。

Heat Kernel Asymptotics for Scaling Limits of Isoradial Graphs

We consider the asymptotics of the discrete heat kernel on isoradial graphs for the case where the time and the edge lengths tend to zero simultaneously. Depending on the asymptotic ratio between time and edge lengths, we show that two different regimes arise: (i) a Gaussian regime and (ii) a Poissonian regime, which resemble the short-time asymptotics of the heat kernel on (i) Euclidean spaces and (ii) graphs, respectively.
