Abstract
In this paper, we determine the Cartier dual of certain finite group schemes of type (p n , ..., p n ), restricting ourselves to positive characteristic p case. They are given by the kernel of certain endomormphisms of the fibre product W l,A ×Spec A … ×Spec A W l,A of the group scheme of Witt vectors of the length l. Moreover we can treat the kernel of the endomorphism of a type F n + a 1Fn-1 + … + a n : W l,A → W l,A as our special class, where F is the Frobenius endomorphism and a k (k = 1, ..., n) are suitable Witt vectors.
