HeatK: A Mathematica Program for Computing Heat Kernel Coefficients
Michael J. Booth
Abstract
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 AvramidiAvramidi:npb91. See http://fermi.pha.jhu.edu/~booth/HeatK/ for source and examples.
