It’s new to me.
Did you just find this paper browsing the arXiv? That's about as reliable as just searching google...
I'm not saying that this guy is necessarily a crank, but, ya know, you can never be too careful.
I'd also consider "quantal algebra" to be a naming conflict with "quantale", which is a certain type of algebraic structure (usually [always?] on a poset).
I had a quick look, but, to be honest, the paper failed to keep my attention long enough to make any meaningful comments. I rarely read a paper from beginning to end even when it is extremely interesting because I end up chasing references halfway through. My spidey sensors were tingling though. The author claims an association to a university but uses a gmail address. This doesn’t mean I judged the paper because of this. I judged the paper based on a brief (but I think sufficient) gloss and THEN noticed this.
My initial thought was that it looked almost like a simple similarity transform of the usual spinor formulation of relativistic quantum mechanics. As you well know, there are few mysteries when it comes to (special) relativistic quantum mechanics and I didn’t see how this paper could get you any closer to general relativistic quantum mechanics.
Nevertheless, if you would like to write up some ideas, I suggest starting out at Ian Durham. Once you’ve got something that looks fairly polished you’re happy with, then start this conversation again. This is the procedure most of us follow when starting a new project or experimenting with new ideas, i.e. start on the personal webs and move stuff as it becomes appropriate. I’ve done this very thing on many occasions, start writing on my personal web and then ask for opinions before moving it over to the nLab. Sometimes I polish and move and THEN ask for opinion, but a good first step is to “polish” before moving to the nLab.
Just a thought…
If two algebras have the same multiplication table, then I’m pretty sure they are the same algebra. That’s why I said it looks like it is related to the standard treatment by a similarity transformation. If you have an algebra with elements $e_i$ satisfying some multiplication table, then transform each element via
$f_i = S^{-1} e_i S$
the $f_i$ satisfy the same multiplication table and there is nothing new accomplished.
Although it is fun to consider “deformations” this way. Urs did this kind of fun stuff a lot many years ago. For example, we can consider
$f_i = exp(-\delta A) e_i exp(\delta A)$and expand around small $\delta$.
Anyway, I still haven’t managed to get past the 5th page, but will give it a try time permitting.
