The local lifting problem for dihedral groups

Abstract

Let G=DpG=D_p be the dihedral group of order 2p2p, where pp is an odd prime. Let kk an algebraically closed field of characteristic pp. We show that any action of GG on the ring k[[y]]k[[y]] can be lifted to an action on R[[y]]R[[y]], where RR is some complete discrete valuation ring with residue field kk and fraction field of characteristic 0.
