HeatK: A Mathematica Program for Computing Heat Kernel Coefficients
Booth, Michael J. · arXiv (Cornell University) · 1998
Heat kernel coefficients encode the short distance behavior of propagators in the presence of background fields, and are thus useful in quantum field theory. We present a Mathematica program for computing these coefficients and their derivatives, based on an algorithm by Avramidi\cite{Avramidi:npb91}. See http://fermi.pha.jhu.edu/~booth/HeatK/ for source and examples.
