Abstract
This paper reviews the relations between algebraic K-theory and topological cyclic homology given by cyclotomic trace. If one, very superficially, views algebraic K-theory as classifying invertible matrices, then the cyclotomic trace records the trace of all powers of matrices. In a more relevant formulation, the topological cyclic homology has the same relationship to Bökstedt’s topological Hochschild homology as Connes’ cyclic homology has to Hochschild homology, and the cyclotomic trace is a topological cyclic version of the Dennis trace map.KeywordsSpectral SequenceHomotopy GroupFinite SubgroupCyclic HomologyDual NumberThese keywords were added by machine and not by the authors.
