Homotopy Theory Seminar - Ernie Fontes
Title: Algebraic K-Theory for 2-Categories: + = S-inverse-S
Speaker: Ernie Fontes, OSU
Abstract: For a symmetric monoidal 2-category S, there is a straightforward 2-categorification of Quillen’s S-inverse-S construction for algebraic K-theory due to Gurski–Johnson–Osorno. We build a 2-category Aut(S) which permits a categorified description of algebraic K-theory that generalizes Quillen’s BGL(R)^+ construction and we show that the two approaches agree. As an application, we produce a new model for K_3(R). This talk represents joint work with Niles Johnson and Nick Gurski.
