colouring job done by :iconarneoog: his attempts simply looked better than mine did...
Though, the formula is by me as always.
It's a reinterpretation of the Mset and a series of 3, where the first one actually is the standard Mandelbrot set.

you might know what the "i" in x+y*i means. It's one of two possible solutions for the squareroot of -1. (the other solution simply is -i ^^)
Additionally, it combines vectors with algebra.
This Complex Algebra can be generalized further in several ways.
One of those extensions can be viewed here.
The rule for i simply is:
i²=-1

there are two more ways to extend this. Here, I chose the one, fewer ppl probably would ever think about:
ε≠0 but ε²=0

(x+yε;)² ->
x->x²
y->2xyε

as you see, this rule creates a nice simple fan pattern. :)

Kudos to your colour-izer, but I daresay I am a lot more swept away by the idea of pursuing the square root of -1 ... :lmao:

:lmao: well the next one will be the other extension. And I plan to do a "cyclic" version :)

What I do not yet understand is, why on earth quaternions, which obviously are an other way to extend complex numbers, have such weird multiplications.

I mean... ok... quaternions cease to have comunicative multiplication, so ij=-ji=k, or something...
but WHY do they have that? xD

Oh dear. What are we to do with the likes of you? :D

Here is a little toy, to pass the time with: [link]

We all are void, I guess... ;P

I know that toy already and use it a lot to simplify my formulae to make things go faster ;)
Thanks anyway :D

oh and that nice little toy doesn't yet calculate with either of the complex extensions...

hmmmmm... tea :D

i think you mean commutative ;P

yes of course xD
Well, could you also answer me that?
Show me a way to proof the uncommuntativity of quaternions... It might help me...
It must follow somehow from the rules that i*j*k=i²=j²=k²=-1

also I'm kinda unsure, how the multiplication rules apply to division...
from i*j=k -> i=k/j and j=k/i ?
so j*i=-k -> j=-k/i and i=-k/i... that kinda doesn't make sense. Or, does it? that would mean, that i=-i which apparently isn't true either...

it comes directly from the definition: [link]

I now did all the multiplications myself and might have found the solution.
Wiki just derives the trivial k=i*j but doesn't directly show, why -k=j*i... It later refers to the cross product implying the reason but... oh well xD

Though, what I did now was this:
first step as Wiki said:
-1=ijk=i²=j²=k²

-i=ijki
-i=-jk
i=jk


-j=ijkj
-j=-ik
j=ik

-k=ijkk
-k=-ij
k=ij

and from those definitions, I went on, replacing each letter by the others:

i=jk, j=ik
i=ikk
i=-i FALSE
i=jk, k=ij
i=jij
i=-i FALSE
i=jk, j=ik, k=ji
i=ikji
i=-kj TRUE

same for the two others...
I wonder if that's the standard way to do the full derive...

it does actually give a derivation of the anticommutative properties, in the section i linked ;P

but of course, it's always best to derive things yourself! :#1:

well I didn't see it... maybe I'm blind xD
Oh well, so, at least I seem to have found the reason. Although it's very easy to do contradictions that way...
