Primes and fields in stable motivic homotopy theory

Abstract

Let $F$ be a field of characteristic different from $2$. We establish surjectivity of Balmer’s comparison map

${\rho }^{\bullet }:\phantom{\rule{0.3em}{0ex}}Spc\left({SH}^{{\mathbb{A}}^{1}\phantom{\rule{0.3em}{0ex}}}{\left(F\right)}^{c}\right)\to {Spec}^{h}\left({K}_{\ast }^{MW}\left(F\right)\right)$

from the tensor triangular spectrum of the homotopy category of compact motivic spectra to the homogeneous Zariski spectrum of Milnor–Witt $K\phantom{\rule{0.3em}{0ex}}$–theory. We also comment on the tensor triangular geometry of compact cellular motivic spectra, producing in particular novel field spectra in this category. We conclude with a list of questions about the structure of the tensor triangular spectrum of the stable motivic homotopy category.
