Resumming heat kernels

Physical Review D, 1992
Summary: A direct method is given for resumming nonderivative terms arising out of the ``Xterms'' from operators of the form \(\nabla^2+X\) in the asymptotic expansions of heat kernels.

Heat Kernels of Graphs

Journal of the London Mathematical Society, 1993
We prove a sharper pointwise upper bound for the heat kernel of the continuous time random walk on a general graph under a weaker assumption than that by \textit{I. Chavel} and \textit{E. A. Feldman} in `Modified isoperimetric constants and large time heat diffusion in Riemannian manifolds', preprint 1990. Our main result is stated in Theorem 2.6.

Heat Kernel Asymptotics

2015
This is the main chapter of the book describing the crucial ingredients of the heat kernel method. It is an enhanced version of the singular perturbation method described in the previous chapter due to a heavy use of geometric techniques. The main goal is to compute the short-time asymptotic expansion of the heat kernel and the corresponding expansion ...
