Re: R-Algebra of dimension 4 and 8

Nice! What I like about the Mironovs' approach is that their framework remains on associative algebra, yet they are able to model fields mediated by spin-1 and

Re: R-Algebra of dimension 4 and 8

Hi everyone, Following Jens's idea I studied Octons and Sedeons algebras and found a matrix representation of the octons (not included in the articles I read),

Re: Correction - Re: Commutativity Invariance

I just noticed I never posted the correction, and a correction is needed indeed. We start with an algebra that is built over a real vector space in n

Correction - Re: Commutativity Invariance

... This is nonsense, I have to think it through.

Re: Commutativity Invariance

I'm not sure ... In my last post I acidentally introduced the property of orthogonal transformations U to be diagonalizable, however, without actually using

Hi Jens This is the multiplication table for generalized quaternion R^4(I,J,A,K) *.|1........x......y.......z --+--------------------------

Re: Commutativity Invariance

Hi Jens Thank you for your notational innovation of * to shorten formulas. Glad that you enjoy my inovation of multiplication matrix :) You're right, it can

Re: Commutativity Invariance

Hi - sorry I just threw out that one comment about linear transformations yesterday, I should have spent a bit more time and brush up on my linear algebra

Re: Commutativity Invariance

Yes this is curious. [Sorry for by belated response, this year I picked up playing chess again after 25 years and am enjoying it too much] In the case of

Re: Commutativity Invariance

Hi Jens, the fact that linear algebra isomorphism can not be represented by linear transformation is new to me. I will study your attached paper more closely.

Re: Commutativity Invariance

Hi Philippe, Thank you for showing my foolishness believing the trace as the signature. It means that I am confused about scalar trace and "vectorial"

Re: Commutativity Invariance

Hi Jens I'd also like to point out that you can have two algebras with identical properties and still will not be able to transform them into one another

Re: Commutativity Invariance

Hi - this is interesting. Next to algebraic properties, I'd also like to point out that you can have two algebras with identical properties and still will not

Hi Arma, I don't get where you are heading to : of course an isomorphism between algebra preserves commutativity, associativity, and so on ... this is the

Commutativity Invariance

Hi all In this letter I will try to prove that isomorphic generalized quaternions are having the same commutativity. Theorem (commutation Invariance)
