Cosimplicial resolutions and homotopy spectral sequences in model categories
A K Bousfield
We develop a general theory of cosimplicial resolutions, homotopy
spectral sequences, and completions for objects in model categories,
extending work of Bousfield-Kan and Bendersky-Thompson for ordinary
spaces. This is based on a generalized cosimplicial version of the
Dwyer-Kan-Stover theory of resolution model categories, and we are
able to construct our homotopy spectral sequences and completions
using very flexible weak resolutions in the spirit of relative
homological algebra. We deduce that our completion functors have
triple structures and preserve certain fiber squares up to
homotopy. We also deduce that the Bendersky-Thompson completions over
connective ring spectra are equivalent to Bousfield-Kan completions
over solid rings. The present work allows us to show, in a subsequent
paper, that the homotopy spectral sequences over arbitrary ring
spectra have well-behaved composition pairings.
