ell-adic topological Jacquet-Langlands duality
Andrew Salch, Matthias Strauch
We embed the Lubin-Tate tower into a larger tower of formal schemes, the "degenerating Lubin-Tate tower." We construct a topological realization of the degenerating Lubin-Tate towe…

KU-local zeta-functions of finite CW-complexes
A. Salch
Begin with the Hasse-Weil zeta-function of a smooth projective variety over the rational numbers. Replace the variety with a finite CW-complex, replace etale cohomology with comple…

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…
