On the algebraic cobordism ring of involutions

Olivier Haution

We consider the cobordism ring of involutions of a field of characteristic not two, whose elements are formal differences of classes of smooth projective varieties equipped with an…

The stable Adams operations on Hermitian K-theory

Jean Fasel, Olivier Haution

We prove that exterior powers of (skew-)symmetric bundles induce a $λ$ -ring structure on the ring $G W^{0} (X) \oplus G W^{2} (X)$ , when $X$ is a scheme where $2$ is invertible. Using this…

Connective K-theory and Adams operations

Olivier Haution, Alexander S. Merkurjev

We investigate the relations between the Grothendieck group of coherent modules of an algebraic variety and its Chow group of algebraic cycles modulo rational equivalence. Those ar…
