Abstract
The topological Hochschild homology of an orthogonal ring spectrum can be defined by evaluating the cyclic bar construction on or by applying Bökstedt's original definition of to . In this paper, we construct a chain of stable equivalences of cyclotomic spectra comparing these two models for . This implies that the two versions of topological cyclic homology resulting from these variants of are equivalent.
