Is the algebraic closure of the rational functions over R a subset of the set of partial functions from R to C?
Thanks Pierre for pointing out that big hole about $P(R,C)$ not having a clear ring structure. I will think about that and see if that can be resolved in a nice way. As for your comment about $\sqrt{x}$, I would say there is no problem since I would define the domain to be $R$ and the codomain to be $C$ so that $\sqrt{−a}=\sqrt{a}i$ for $a>0$. |

In the last post I made the question more well-defined and in this one added a mention of what kind of answer I am looking for. |

Sorry for the ambiguity, I have made what I meant much more precise now. This kinda of problem seems like that kind that has a clear answer and a method of construction as well. |

Looking for methods to solve multivariate non-traditional polynomial sequence recurrence relations
Sounds like the approach is inherently one of algebraic geometry. Are there any standard ways of computing what the roots for polynomials in these fields would be? I would expect we would need a generalized notion of a radicals. And if an expression for the solutions don't always exist, would it be out of the question to look for an approximation to the roots which live in the closure of $Frac(Z[s,t,p])$ by using elements of the closure of $Frac(R[s,t,p])$? |
