| Mar 5, 2017 at 1:16 | comment | added | Marc Hoyois | @Denis It doesn't actually. The typical example is there's a basis of the topology on the Hilbert cube with a different ∞-category of sheaves. @ Karthik There are some sufficient conditions in Lemma C.3 in my paper math.mit.edu/~hoyois/papers/lefschetz.pdf. They're not very satisfying because they require existence of some pullbacks, but they suffice in many situations. | |
