Heat Kernel Asymptotics for Scaling Limits of Isoradial Graphs
Heat Kernel Asymptotics for Scaling Limits of Isoradial Graphs
Abstract 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) …
