Algebraic K-theory and descent for blow-ups

  • Moritz KerzEmail author

We prove that algebraic K-theory satisfies ‘pro-descent’ for abstract blow-up squares of noetherian schemes. As an application we derive Weibel’s conjecture on the vanishing of negative K-groups.



Ofer Gabber suggested to us to use derived algebraic geometry in order to generalize Thomason’s calculation of the K-theory of a blow-up in a regularly immersed center, see Sect. 3. We would like to thank him for this essential remark. We would like to thank Matthew Morrow for several helpful discussions about his work on pro-calculations in K-theory. Finally, we thank the referee for his or her careful reading of the manuscript and several comments to improve the presentation.
