Compactly supported -Euler characteristics of symmetric powers of cellular varieties
Jesse Pajwani, Herman Rohrbach, Anna M. Viergever
The compactly supported -Euler characteristic, introduced by Hoyois and later refined by Levine and others, is an anologue in motivic homotopy theory of the classical…
Atiyah-Segal completion for the Hermitian K-theory of Symplectic Groups
Jens Hornbostel, Herman Rohrbach, Marcus Zibrowius
We study equivariant Hermitian K-theory for representations of symplectic groups, especially . The results are used to establish an Atiyah-Segal completion theorem f…
Hermitian K-theory of Grassmannians
Herman Rohrbach
We compute the additive structure of the Hermitian -theory spectrum of an even-dimensional Grassmannian over a base field of characteristic zero in terms of the Hermitian $K…
On Atiyah-Segal completion for T-equivariant Hermitian K-theory
Herman Rohrbach
We show how derived completion can be used to prove an analogue of Atiyah-Segal completion for the -equivariant Hermitian K-theory of a scheme with a trivial -action, con…
