DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HKUST-AG/46/
 ">Higher Segal spaces and algebraic structures</a>\nby Walker Stern (Bilke
 nt University) as part of Algebra and Geometry Seminar @ HKUST\n\nLecture 
 held in 3598.\n\nAbstract\nIn this talk\, I will introduce the 2-Segal con
 ditions of Dyckerhoff and Kapranov\, describing both the algebraic and geo
 metric intuitions which lead to the 2-Segal conditions. I will then give a
 n overview of how the algebraic intuition can be extended to classify vari
 ous algebraic structures in (higher) categories of spans. I will additiona
 lly explain how the geometric intuition can be used to provide state-sum-s
 tyle invariants of surfaces. Time permitting\, I will then discuss work in
  progress on higher cyclic operads\, inspired by intuitions which arise fr
 om the algebraic characterization of 2-Segal objects.\n
