Is there a reliable freeware program for Windows XP Pro to do traces
of gamma matrix products? I've tried Google, but couldn't find a search phrase that was precise enough to find anything useful. TIA Don Ritchie

The following are free software packages that have some facility for dealing with the algebra of Dirac gamma matrices: Maxima, http://maxima.sourceforge.net/ Axiom, http://wiki.axiomdeveloper.org/FrontPage GiNaC, http://www.ginac.de/ I believe all of them work on Windows. However, if you decide to use any one of them, you'll have to spend some time learning to use the provided environment. There also seem to be addon packages for commercial computer algebra systems that do the trick: Maple, http://asiver.chat.ru/ Mathematica, http://library.wolfram.com/infocenter/MathSource/435/ Reduce, www.reducealgebra.com/docs/cvit.pdf Hope this helps.
