摘要
Let (G,E) be a graph with weights {a(xy)} for which a parabolic Harnack inequality holds with space-time scaling exponent betagreater than or equal to2. Suppose {a'(xy)} is another set of weights that are comparable to {a(xy)}. We prove that this parabolic Harnack inequality also holds for (G,E) with the weights {a'(xy)}. We also give stable necessary and sufficient conditions for this parabolic Harnack inequality to hold.
