  The Drinfeld formal group and THH

  Drinfeld has defined a certain formal group closely related to the prismatization of G_m and to the theory of Chern classes in prismatic cohomology. I'll explain how to identify this formal group with one obtained from THH and chromatic homotopy theory. I'll also explain how this identification, together with a Lichtenbaum–Quillen property for syntomic cohomology, yields an "algebraization" of this formal group conjectured by Drinfeld.
