WebA weak Grothendieck topology is a category with a notion of covering which satisfie als l but the composition axiom for Grothendieck topologies. A sheaf with respec tto a weak Grothendieck topolog hays the obvious meaning. Certainl it also makey s sense to speak of the (weak) Grothendieck topology generate bdy a partial collection of "coverings". WebA Grothendieck topology J on a category C is a collection, ... Note that for this definition C is not required to have a topology. A sheaf on a site, however, should allow gluing, just like sheaves in classical topology. ... Artin, Michael (1962).

In the nineties, Berkovich developed his spectral theory of non-archimedean spaces. His spaces carry a true topology, which allows to apply classical techniques from 1 maniacci attorneyWebHe was a student of Grothendieck in the 1960’s. His main poles of interest are group schemes, Néron models and rigid geometry.

A Grothendieck topology is basically what you get when you ask for a category which behaves like the category of open sets in the sense that it has a good notion of covering. What do I mean by this? maniacci
