Completed power operations for Morava E–theory

Tobias Barthel; Martin Frankland

We construct and study an algebraic theory which closely approximates the theory of power operations for Morava E-theory, extending previous work of Charles Rezk in a way that takes completions into account. These algebraic structures are made explicit in the case of K-theory. Methodologically, we emphasize the utility of flat modules in this context, and prove a general version of Lazards flatness criterion for module spectra over associative ring spectra.

Behavior of Quillen (co)homology with respect to adjunctions

Martin Frankland

This paper aims to answer the following question: Given an adjunction between two categories, how is Quillen (co)homology in one category related to that in the other? We identify the induced comparison diagram, giving necessary and sufficient conditions for it to arise, and describe the various comparison maps. Examples are given. Along the way, we clarify some categorical assumptions underlying Quillen (co)homology: cocomplete categories with a set of small projective generators provide a convenient setup.

Higher Toda brackets and the Adams spectral sequence in triangulated categories

J. Daniel Christensen; Martin Frankland

The Adams spectral sequence is available in any triangulated category equipped with a projective or injective class. Higher Toda brackets can also be defined in a triangulated category, as observed by B. Shipley based on J. Cohens approach for spectra. We provide a family of definitions of higher Toda brackets, show that they are equivalent to Shipleys, and show that they are self-dual. Our main result is that the Adams differential

Martin Frankland

Abstract Using the obstruction theory of Blanc, Dwyer and Goerss, we compute the moduli space of realizations of 2-stage Π-algebras concentrated in dimensions 1 and n or in dimensions n and n + 1 . The main technical tools are Postnikov truncation and connected covers of Π-algebras, and their effect on Quillen cohomology.
