Hello, I live near Boston, Massachusetts and am just getting started with tensor algebra using Mathematica. I could use some help!
In particular, please see the problem I am starting with at my website. An acquaintance of mine showed me how to solve this problem using the "FeynCalc" add-on to Mathematica, and his solution is also at my website. How can I solve this problem using Mathematica without any add-on like FeynCalc?
I do research at a small nonprofit organization, The Institute for Intermediate Study (TIFIS). If you can show me how to solve this problem without FeynCalc, just using Mathematica's built-in tensor software, that would get me off to a great start. The problem I'm having with FeynCalc is that it seems to require me to be online to some extent, even after downloading the software, whereas I would like to just work offline. My email address is andrewthyman@gmail.com. Thanks.
