We will see that a certain class of six-functor formalisms, those which have recollements, can be considered a higher categorical analogue of compactly supported cohomology. As a result, we see that such a six-functor formalism can be recovered from its restriction to complete varieties.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Time: 11:00 AM Recording:https:\/\/us02web.zoom.us\/rec\/share\/9f42mPT6f_DrAb7PSelgFJxj4VF5XyBFR_w9Q_1pmd0l7N8vBrZA5s9tHsXNyc-I.WUIy_fbLn_vZCL1l Abstract: In the first part of this talk I will discuss a result about the existence of compactly supported versions of cohomology theories of varieties.
