Vova Sosnilo (Regensburg) - Witt vectors and localizing invariants

In 80s Weibel observed that K-theory is homotopy invariant on Fp-schemes up to p-torsion. His main tool was the action of the ring Witt vectors on nil-K-groups: NKi(R) = Ker(Ki(R[t]) → Ki(R)). We will revisit the proof and check that the same result holds for all finitary localizing invariants.
