DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BilTop/117/"
 >Abacus bicomodule configurations and the Bergner–Osorno–Ozornova–Ro
 velli–Scheimbauer equivalence</a>\nby Thomas Jan Mikhail (University of 
 Copenhagen) as part of Bilkent Topology Seminar\n\nLecture held in SA 141.
 \n\nAbstract\nA theorem of Bergner\, Osorno\, Ozornova\, Rovelli\, and Sch
 eimbauer states an equivalence between 2-Segal spaces and certain augmente
 d stable double Segal spaces. In this talk\, after a preliminary section o
 n 2-Segal spaces\, I will establish more general equivalences\, involving 
 simplicial maps of 2-Segal spaces and abacus bicomodule configurations\, e
 xtending results of Carlier. This talk is based on joint work with Joachim
  Kock\, and a preprint of this work is available on the arXiv (see arXiv:2
 501.16491).\n
