Twisted ambidexterity in equivariant homotopy theory
B Cnossen - arXiv preprint arXiv:2303.00736, 2023 - arxiv.org
We develop the concept of twisted ambidexterity in a parametrized presentably symmetric
monoidal $\infty $-category, which generalizes the notion of ambidexterity by Hopkins and …

-Topoi and descent
We set the foundations of a theory of Grothendieck $(\infty, 2) $-topoi based on the notion of
fibrational descent, which axiomatizes both the existence of a classifying object for fibrations …
