MATH Seminar: “$(infty,2)$-categories and lax colimits”, Walker Stern, 1:30PM November 27 (EN)

You are cordially invited to the Topology Seminar organized by the Department of Mathematics.

Speaker: Walker Stern (Bilkent University)
“$(infty,2)$-categories and lax colimits”

Abstract: Many higher-categorical structures, most notably $(infty,1)$-categories themselves, form $(infty,2)$-categories. It is thus highly desirable to characterize such structures in terms of $(infty,2)$-categorical universal properties. One recent framework allowing us to understand such $(infty,2)$-categorical universal properties is the theory of (co)limits in $(infty,2)$-categories. In this talk, I will explain the developing theory of (partially) lax colimits in $(infty,2)$-categories, and discuss how it recovers a number of previous notions in the literature. I will then explain how one can generalize from the $(infty,1)$-categorical setting to obtain a cofinality criterion for $(infty,2)$-functors. This work was joint with Fernando Abellán.
