Abstract
Let be an algebraically closed field of characteristic . In this paper we describe the -actions on for which there is a discrete valuation ring , a finite extension of the ring of Witt vectors , such that they can be lifted as a group of -automorphisms of . In fact the necessary and sufficient condition for such an action to lift involves only the conductor type of the corresponding extension.
