[HTML][HTML] Hermitian K-theory for stable -categories I: Foundations

B Calmès, E Dotto, Y Harpaz, F Hebestreit, M Land… - Selecta …, 2023 - Springer
This paper is the first in a series in which we offer a new framework for hermitian K-theory in
the realm of stable∞-categories. Our perspective yields solutions to a variety of classical …

[PDF][PDF] Hermitian K-theory for stable∞-categories II: Cobordism categories and additivity

B Calmes, E Dotto, Y Harpaz… - arXiv preprint …, 2020 - bcalmes.perso.math.cnrs.fr
We define Grothendieck-Witt spectra in the setting of Poincaré-categories and show that
they fit into an extension with a K-and an L-theoretic part. As consequences, we deduce …

Stable moduli spaces of hermitian forms

F Hebestreit, W Steimle - arXiv preprint arXiv:2103.13911, 2021 - arxiv.org
We prove that Grothendieck-Witt spaces of Poincar\'e categories are, in many cases, group
completions of certain moduli spaces of hermitian forms. This, in particular, identifies …

[PDF][PDF] Hermitian K-theory for stable∞-categories III: Grothendieck-Witt groups of rings

B Calmes, E Dotto, Y Harpaz… - arXiv preprint …, 2020 - bcalmes.perso.math.cnrs.fr
We establish a fibre sequence relating the classical Grothendieck-Witt theory of a ring 𝑅 to
the homotopy C2-orbits of its K-theory and Ranicki's original (non-periodic) symmetric L …

Hermitian K-theory for stable -categories II: Cobordism categories and additivity

B Calmès, E Dotto, Y Harpaz, F Hebestreit… - arXiv preprint arXiv …, 2020 - arxiv.org
We define Grothendieck-Witt spectra in the setting of Poincar\'e $\infty $-categories and
show that they fit into an extension with a K-and an L-theoretic part. As consequences we …

A motivic spectrum representing hermitian K-theory

B Calmès, Y Harpaz, D Nardin - arXiv preprint arXiv:2402.15136, 2024 - arxiv.org
We establish fundamental motivic results about hermitian K-theory without assuming that 2
is invertible on the base scheme. In particular, we prove that both quadratic and symmetric …
