Cdh descent, cdarc descent, and Milnor excision

Elden Elmanto, Marc Hoyois, Ryomei Iwasa +1

We give necessary and sufficient conditions for a cdh sheaf to satisfy Milnor excision, following ideas of Bhatt and Mathew. Along the way, we show that the cdh infinity-topos of a…

Ryomei Iwasa, Wataru Kai

In this note, we establish isomorphisms up to bounded torsion between relative $K_{0}$ -groups and Chow groups with modulus as defined by Binda-Saito.
