dc.description.abstractLet k be a perfect field of positive characteristic, k(t)per the perfect closure of k(t) and A = k[[X1, . . . , Xn]]. We show that for any maximal ideal n of A′ = k(t)per ⊗k A, the elements in Ac′ n which are annihilated by the “Taylor” Hasse-Schmidt derivations with respect to the Xi form a coefficient field of Ac′ n .es
