Discrete version of Dungey’s proof for the gradient heat kernel estimate on coverings

Satoshi Ishiwata (2007)

Annales mathématiques Blaise Pascal

We obtain another proof of a Gaussian upper estimate for a gradient of the heat kernel on cofinite covering graphs whose covering transformation group has a polynomial volume growth. It is proved by using the temporal regularity of the discrete heat kernel obtained by Blunck [2] and Christ [3] along with the arguments of Dungey [7] on covering manifolds.
