Ravenel's Global Conjecture is true
A. Salch
I prove Ravenel's 1983 "Global Conjecture" on $\Ext^1$ over the classifying Hopf algebroid of formal -modules, equivalently, the first flat cohomology group of the mo…
Ravenel's algebraic extensions of the sphere spectrum do not exist
A. Salch
In this paper we prove a topological nonrealizability theorem: certain classes of graded -modules are shown to never occur as the -homology of a spectrum. Many of these $…
Failure of flat descent of model structures on module categories
Andrew Salch
We prove that the collection of model structures on (quasicoherent) module categories does not obey flat descent. In particular, it fails to be a separated presheaf, in the fppf to…
The Hochschild homology and cohomology of A(1)
Andrew Salch
We compute the Hochschild homology and cohomology of , the subalgebra of the -primary Steenrod algebra generated by the first two Steenrod squares, and . The…
The Bousfield localizations and colocalizations of the discrete model structure
A. Salch
We compute the Bousfield localizations and Bousfield colocalizations of discrete model categories, including the homotopy categories and the algebraic -groups of these localizat…
