dc.description.abstract	Let A be any associative ring, possibly non-commutative and let p be a prime number. Let E(A)be the ring of p-typical Witt vectors as constructed by Cuntz and Deninger in [1] E(A)and be that constructed by Hesselholt in [3]. The goal of this paper is to answer the following question by Hesselholt: IsHH0(E(A))∼=W(A)We show that in the case , there is no such isomorphism possible if one insists that it be compatible with the Verschiebung operator and the Teichmüller map.	en_US
