Participating: Ryomei Iwasa (University of Copenhagen)

Abstract: I will report a joint work in progress with Toni Annala. I will explain a characterization of algebraic K-theory of schemes by projective bundle formula: More precisely, algebraic K-theory is an initial Zariski sheaf of ring spectra which is equipped with a multiplicative map from \(BG_m\) and satisfies the projective bundle formula.
