摘要
The ring of p-typical Witt vectors is an indispensable tool in number theory and mixed characteristic commutative algebra. Witt vectors were significantly generalized by Dress and Siebeneicher by producing for any profinite group G, a ring-valued functor W-G. The p-typical Witt vectors are recovered as the example G = Z(p). This paper explores the structure of the ring W-D2 infinity (k) where k is a field of characteristic 2 and D-2 infinity := (lim) under left arrow D-2n.
