โœฆ Synopsis


Locally nilpotent derivations of the polynomial ring in n variables over the complex field, algebraic actions of the additive group G. of complex numbers on C", and vector fields on C" admitting a strictly polynomial flow, are equivalent objects. The polynomial centralizer of the vector field corresponding to a triangulable locally nilpotent derivation is investigated, yielding a tiangulability criterion. Several new examples of nontriangulable Ga actions on C" are presented.

Given a UFD R containing the rational numbers, we study locally nilpotent w x R-derivations of the polynomial ring R X, Y ; in particular, we give a generalization of Rentschler's Theorem and a criterion for the existence of a slice. These results are then applied to describe rank two locally nilpot
