# Vova Sosnilo (Regensburg) - Witt vectors and localizing invariants

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