I solved the problem myself. In case anyone else needs to deal with this issue, the solution is to convert the inert differential operator Diff to diff using the Maple function value(%). Apparently indices cannot contract over the inert differential operator, which is silly. Inert clearly...

I have been using Maple for a decade, but only recently started using the Physics Package. I unfortunately ran into trouble to contract indices ( Maple calls it SumOverRepeatedIndices ). Below I give an example that will execute if you paste it into a Maple worksheet. A metric is defined. A...

Looks reasonable thanks. Just one contradiction. A Ph.D. (Doctor of Philosophy) in Mathematics/Physics e.g. is a study in Philosophy, as to create new work does involve the highest form of Philosophy with the end result verifiable new facts. The latter is what distinguishes this Philosophy...

Thank you. Do you have a list of forum rules I can read ?

I am currently a PhD student,
