John Rognes (UiO): Topological Cyclic Homology of the integers, and related topics

Abstract: 

We calculate TC(Z), K(Z_p), K(Q_p) and K^et(Q_p) mod p (and v_1), as well as the associated graded syntomic, motivic and Galois cohomology groups, illustrating local Tate duality at the group and spectrum levels, as well as two Lagrangian refinements of this duality.
