DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BilTop/60/">
 A story about spans</a>\nby Walker Stern (The University of Virginia) as p
 art of Bilkent Topology Seminar\n\nLecture held in SB-Z11.\n\nAbstract\nSp
 ans in a category C arise in a variety of disparate contexts\, from the st
 udy partially defined functions between sets to Lagrangian correspondences
  in symplectic geometry. In this talk\, I will give an overview of some of
  these connections and tell a story which leads from algebras in categorie
 s of spans to operads. Along the way\, I will discuss past and ongoing wor
 k (part of the latter joint with Ivan Contreras and Rajan Mehta) analyzing
  and classifying various algebraic structures in spans.\n
