Construction of the motivic cellular spectrum ${\mathbf{KO}}^{geo}$ over $Spec(\mathbb{Z})$

K. Arun Kumar

We construct a periodic motivic spectrum over $Spec(\mathbb{Z})$ which when pulled back to any scheme $S$ with $\frac{1}{2}\in \hat{I}“(S,{\mathcal{O}}_S)$ is the $H{P}^1-$spectrum constructe…
