Degree reduction under specialization
The main application of this paper is the resolution of some parametric systems of polynomial equations. This is done looking for which information remains in a Gröbner basis under specialization. Let \(R\) be a ring and let \(\varphi:R[x] \rightarrow R[x]\) be a specialization, i.e. a ring homomorphism such that \(\varphi(x) = x\). For any \(f \in R[x]
