On the Automorphism Group of a polynomial differential ring in two variables
Resumen:
We consider differential rings of the form (K[x, y],D), where K is an algebraically closed field of characteristic zero and D : K[x, y] / K[x, y] is a K-derivation. We study the Automorphism Group of such a ring and give criteria for deciding whether that group is an algebraic group. In most cases, from that study we deduce a primary classification of this type of differential ring up to conjugation with a polynomial automorphism.
