Originally, the Updates contained only changes to the Physics package, and, by chance, I tightened the update of the "date of a version" to saving the Physics package. The project, however, quickly evolved into Updates that could involve changes to any part of the Maple library, but the update of the version's date still only happened when Physics was saved. Since the recent versions of the Updates involved changes that didn't require saving Physics, the version date didn't change. In the latest one (from today) the version's date reappears correct.

Best wishes for 2025!

As explained in a comment, this was a problem related to recent fixes in Typesetting, introduced in v.1835. This change now resolves that problem. To install the corrected version, as usual, input Physics:-Version(latest);

Thanks for the report; this one is fixed. To install the fix in Maple 2024, as usual, input Physics:-Version(latest);

I also don't like unnecessary brackets. I touched the Typesetting so that, at least for this example, we do not have unnecessary brackets anymore. To install, as usual, input Physics:-Version(latest). Now, the Typesetting code is tricky; could you please help posting here:

• More cases of unnecessary brackets.
• Any case you think the brackets are missing, so the opposite situation.

Thanks

Now, clearly, "no output at all", was a bug. I don't know what you actually meant by "Did Maple always behave this way for Laplace?"

On your comparison with Maple competitors, Mathematica or any other one, I'd like to make a point clearly: neither it produces shame nor urgency. Actually, when I read these strange comparisons (like a bug with a no-bug), I personally dislike the communication style. For me, it is just not constructive or purposeless, making me automatically lower the issue's priority. Fixing issues on the fly, as is the case of the Maplesoft Physics Updates project, has the underlying idea of collaboration and excitement, say, the opposite of such adversarial comparisons of inequivalent things.

Section 7 of ?Physics,Tensors is called Inert Tensors. Regarding a tensor definition, e.g. for Ricci or any other one, also the ones you define using defining equations, to see the definition even when the tensor has all of its components equal to zero, use the 'definition' keyword to index the tensor, e.g. input Ricci[definition].

With a signature where the timelike component is in position 4, e.g. (---+), both X[4] and X[0] return t, so yes you can count starting from 0. If the timelike component is in position 1, then no, you cannot start counting from 0.

I understand this command does what you want to do, i.e. sort by rank. An equivalent command may be in the Grobner or RegularChains packages.

Regardless of RootOf's caching approach, this error interruption should not happen in the first place. The problem is fixed, and the fix is distributed within the Maplesoft Physics Updates v.1808 or newer. To install, open Maple and input Physics:-Version(latest)

Using directly Maple TTY to avoid any interference: no error message.

I suggest you to revise you don't have anything interfering, and if you still see this error message you posted, then input 'tracelast;' and post its output here so that I could see how this message you get is produced. If entering tracelast results in nothing, executing the odetest line again, reproducing the error, then tracelast again.

Hi @nm
Note first that you show how to compute an implicit solution, for which dsolve([ode, IC], implicit) works fine and returns, exactly, the solution you show as my_new_sol.

The problem was related to computing an explicit solution, a process involving computing a series that happened to interrupt with that error you saw. That problem is solved and the adjustment is distributed within the latest Maplesoft Physics Updates for Maple 2024. (install via Physics:-version(latest))
