摘要
We prove that the functor ring-of-rational-Witt-vectors W (0)(-) becomes co-representable in the category of noncommutative motives. As an application, we obtain an immediate extension of W (0)(-) from commutative rings to schemes. Then, making use of the theory of noncommutative motives, we classify all natural transformations of the functor K-theory-of-automorphisms.
