DESCRIPTION:Speakers: Shay Ben Moshe (MPIM)\n\nAbstract Homotopy Theory Se
 minar\nLimits of ∞-categories are usually much easier to compute than co
 limits. Nevertheless\, in Pr^L\, limits and colimits indexed by a space co
 incide as proven by Lurie. Harpaz has shown a similar phenomenon for ∞-c
 ategories with π-finite colimits\, which plays an important role in the t
 heory of higher semiadditivity. In this talk\, I will explain a common gen
 eralization of these results. Surprisingly\, the proof will make use of th
 e (∞\,3)-category of iterated spans\, and its universal property due to 
 Stefanich\, which encodes such ambidexterity phenomena in a coherent fashi
 on.\n\nhttps://math-events.uni-bonn.de/event/1291/
