\u201cAbacus bicomodule configurations and the Bergner\u2013Osorno\u2013Ozornova\u2013Rovelli\u2013Scheimbauer equivalence\u201d<\/p>\n

Abstract: A theorem of Bergner, Osorno, Ozornova, Rovelli, and Scheimbauer states an equivalence between 2-Segal spaces and certain augmented stable double Segal spaces. In this talk, after a preliminary section on 2-Segal spaces, I will establish more general equivalences, involving simplicial maps of 2-Segal spaces and abacus bicomodule configurations, extending 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:2501.16491).<\/p>\n

Date: July 7, Monday, 2025
