Spectra of units for periodic ring spectra and group completion of graded E-infinity spaces
Steffen Sagave
We construct a new spectrum of units for a commutative symmetric ring spectrum that detects the difference between a periodic ring spectrum and its connective cover. It is augmente…

Group completion and units in I-spaces
Steffen Sagave, Christian Schlichtkrull
The category of I-spaces is the diagram category of spaces indexed by finite sets and injections. This is a symmetric monoidal category whose commutative monoids model all E-infini…

Diagram spaces and symmetric spectra
Steffen Sagave, Christian Schlichtkrull
We present a general homotopical analysis of structured diagram spaces and discuss the relation to symmetric spectra. The main motivating examples are the I-spaces, which are diagr…
