AbstractAn action of a finite group A/pP for a prime p on the affine plane A2 in characteristic zero can be deformed to an action of the local group scheme μp on A2 in positive characteristic. Given an action of μp on A2, one may ask conversely when this action is a deformation of an action of Z/pZ. We shall show that the linearizability condition of the action of μp is a good candidate for a necessary and sufficient condition
