Hello Martin, > I am therefore looking for another way to combine these algebras in > interesting ways.
If you look at real Clifford algebras, and within them at spinor modules (vector spaces) then you can model all of the required number systems as sub Clifford alegbras. So if that is your only venue you need only Clifford algebras over Clifford numbers. > zeros of x^2+1, but I can't think how polynomials could represent dual > or double numbers and so on? What about R[x]/<x^2> and R[x]/<x^2-1> ?
