Abstract

Weibel proved that pp-inverted K-theory is A1\mathbb{A}^1-invariant on Fp\mathbb{F}_p-schemes and K-theory with Z/p\mathbb{Z}/p-coefficients is A1\mathbb{A}^1-invariant on Z[1p]\mathbb{Z}[\frac{1}{p}]-schemes. We extend this result to all finitary localizing invariants of small stable \infty-categories. Along the way we study the Frobenius and Verschiebung endofunctors defined by Tabuada and provide a categorical version of Stienstra's projection formula.
