Higher homotopy invariants for spaces and maps

David Blanc, Mark W. Johnson, James M. Turner

For a pointed topological space , we use an inductive construction of a simplicial resolution of by wedges of spheres to construct a "higher homotopy structure" for (in…

A constructive approach to higher homotopy operations

David Blanc, Mark W. Johnson, James M. Turner

In this paper we provide an explicit general construction of higher homotopy operations in model categories, which include classical examples such as (long) Toda brackets and (iter…

Higher homotopy operations and André-Quillen cohomology

David Blanc, Mark W. Johnson, James M. Turner

There are two main approaches to the problem of realizing a -algebra (a graded group equipped with an action of the primary homotopy operations) as the homotopy groups of a…

Higher homotopy operations and cohomology

David Blanc, Mark W. Johnson, James M. Turner

We explain how higher homotopy operations, defined topologically, may be identified under mild assumptions with (the last of) the Dwyer-Kan-Smith cohomological obstructions to rect…

On local-to-global spectral sequences for the cohomology of diagrams

David Blanc, Mark W. Johnson, James M. Turner

The aim of this paper is to construct and examine three candidates for local-to-global spectral sequences for the cohomology of diagrams of algebras with directed indexing. In each…

On realizing diagrams of Pi-algebras

David Blanc, Mark W Johnson, James M Turner

Given a diagram of Pi-algebras (graded groups equipped with an action of the primary homotopy operations), we ask whether it can be realized as the homotopy groups of a diagram of…
