Exterior power operations on higher $K$-groups via binary complexes

Tom Harris, Bernhard Köck and Lenny Taelman

Vol. 2 (2017), No. 3, 409–450

We use Grayson’s binary multicomplex presentation of algebraic K-theory to give a new construction of exterior power operations on the higher K-groups of a (quasicompact) scheme. We show that these operations satisfy the axioms of a λ-ring, including the product and composition laws. To prove the latter we show that the Grothendieck group of the exact category of integral polynomial functors is the universal λ-ring on one generator.
