Units of ring spectra and their traces in algebraic $K$–theory

Abstract

Let GL1(R) be the units of a commutative ring spectrum R. In this paper we identify the composition

ηR: BGL1(R) K(R) THH(R) Ω(R),

where K(R) is the algebraic K–theory and THH(R) the topological Hochschild homology of R. As a corollary we show that classes in πi1R not annihilated by the stable Hopf map η π1s(S0) give rise to non-trivial classes in Ki(R) for i 3.

Keywords
ring spectra, algebraic K-theory, topological Hochschild homology
