Topological Cyclic Homology Via the Norm
Topological Cyclic Homology Via the Norm
We describe a construction of the cyclotomic structure on topological Hochschild homology ( THH ) of a ring spectrum using the Hill-Hopkins-Ravenel multiplicative norm. Our analysis takes place entirely in the category of equivariant orthogonal spectra, avoiding use of the Bökstedt coherence machinery. We are also able to define two …
