Description

We solve Conjecture 10 in Voevodsky's list of open problems in stable motivic homotopy theory. The new ingredient is, surprisingly, prismatic cohomology. My talk will focus on prismatic techniques rather than specifics about motivic homotopy theory.

This is joint work with Tom Bachmann and Matthew Morrow.
