摘要

In this paper, we give estimates on the heat kernel on the diagonal in terms of exp [ - \Log t\alpha], alpha > 1 when t vanishes. Moreover, we compute, by means of the stochastic calculus of variations, the decay of the flatness of some heat kernels. On the other hand, we show that the computations in both cases are very similar.
