Abstract
In arXiv:0805.0157v5, the authors define a class of derived stacks, called "perfect stacks" and show that for this class the categories of quasi-coherent sheaves satisfy a categorical K\"unneth formula. Motivated to extend their results to the theory of analytic stacks as developed by Clausen-Scholze, we investigate categorical K\"unneth formulas for general -functor formalisms. As applications we show a general Tannakian reconstruction result for analytic stacks and, following recent work of Ansch\"utz, Le Bras and Mann arXiv:2412.20968v1, show a -adic version of Drinfeld's lemma for certain stacks that appear conjecturally in a categorical -adic Langlands program.
