Sorry Fred, you are not on MathSciNet.

Does this look like a face that cares whether or not I'm on MathSciNet?

That does not make you a mathematician. You are a retired statistician, and that is about it.

And proud of it, too! Retired member of the Royal Dutch Academy of Sciences; past president of the Dutch society for statistics and O.R.; elected member of the Institute of Physics, and of FQXi; ... now enjoying my retirement.

And continuing to make extremely elementary mathematical mistakes over and over again, as I have exposed here: https://www.academia.edu/38423874/Refut ... ls_Theorem.

Bravo!

More nonsense from Gill continues. I would advise him to stick with statistics. Don't try to be a jack of all trades.

A professor of Engineering and Computer Science from a well-known Canadian University has taken an active interest in my "octonian-like" paper that Gill had campaigned to have retracted from the journal Communications in Algebra. Here is the abstract of the professor's paper, which he has written with one of his Ph.D. students:

Using elementary linear algebra, this paper clarifies and proves some concepts about the previously introduced octonion-like associative division algebra (pseudo-octonion algebra). For a specific seminorm described in the paper (which differs from the norm used in the original paper), it is shown that the pseudo-octonion algebra is a semi-normed algebra, which does not contradict Hurwitz’s theorem. Moreover, additional results related to the computation of inverse numbers in the pseudo-octonion algebra are introduced in the paper, confirming that the pseudo-octonion algebra is a division algebra with no zero divisors using the seminorm. The elementary linear algebra descriptions also allow straightforward software implementations of the pseudo-octonion algebra.

I have read his paper, but it is not yet available online. I will post a link here when it becomes available. My original paper is available on the arXiv: https://arxiv.org/pdf/1908.06172.pdf.

I have posted Gill's retraction saga (involving John C. Baez) on PubPeer for the future historians and sociologists of science: https://pubpeer.com/publications/E3CC09 ... 5CAEE98D#5.

The paper has now appeared online: https://arxiv.org/ftp/arxiv/papers/2012/2012.11359.pdf.

You obviously have to have sufficient mathematical background to be able to check what's written in specialist mathematical articles on Wikipedia. Good articles contain references to every asserted fact. Those two particular articles are pretty good. The split bi-quaternions have been known since Clifford wrote about them in 1873 (he called them "elliptic biquaternions"). He classified all the geometric algebras in 1882. The hypercomplex numbers have similarly been intensively studied for a long time now.

The last version I saw has a pseudo-norm (or semi-norm) instead of a norm. It reduces the space to the quaternions.
