DESCRIPTION:Speakers: Merlin Christ (University of Bonn)\n\nThis is the th
 ird talk on the topic of full exceptional collections in k-linear stable i
 nfinity-categories and perverse schobers. In this talk\, we will show that
  every proper k-linear stable infinity-category with a full exceptional co
 llection arises as the global sections of a perverse schober parametrized 
 by a linear graph. For this\, we will pass through an infinity-categorical
  version of Seidel's directed category construction and a version of Calab
 i-Yau completion. The original exceptional collection will correspond to t
 he collection of standard objects constructed via induction in talk 2.Fina
 lly\, we will introduce a duality for perverse schobers on the once-marked
  disc\, that maps standard objects to costandard objects.\n\nhttps://math-
