Descent for sheaves on compact Hausdorff spaces

Peter J. Haine

These notes explain some descent results for -categories of sheaves on compact Hausdorff spaces and derive some consequences. Specifically, given a compactly assembled $\in…

Pyknotic objects, I. Basic notions

Clark Barwick, Peter Haine

Pyknotic objects are (hyper)sheaves on the site of compacta. These provide a convenient way to do algebra and homotopy theory with additional topological information present. This…

On coherent topoi & coherent -localic -topoi

Peter J. Haine

In this note we prove the following useful fact that seems to be missing from the literature: the -category of coherent ordinary topoi (in the sense of SGA4) is equivalent…

Exodromy for stacks

Clark Barwick, Peter Haine

In this short note we extend the Exodromy Theorem of arXiv:1807.03281 to a large class of stacks and higher stacks. We accomplish this by extending the Galois category construction…

Extended étale homotopy groups from profinite Galois categories

Peter J. Haine

In this note we show that the protruncated shape of a spectral -topos is a delocalization of its profinite stratified shape. This gives a way to reconstruct the extended ét…

Exodromy

Clark Barwick, Saul Glasman, Peter Haine

Let be a quasicompact quasiseparated scheme. Write for the category whose objects are geometric points of and whose morphisms are specializations in…
