Degree reduction under specialization
Journal of Pure and Applied Algebra, 2001 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]

Potential Good Reduction of Degree 2 Rational Maps [PDF]
, 2012 We give a complete characterization of degree two rational maps on P1 with potential good reduction over local fields. We show this happens exactly when the map corresponds to an integral point in the moduli space M2.
