Projective spaces over $\mathbb{F}_{1^{\ell}}$

Abstract

In this essay we study various notions of projective space (and other schemes) over F1\mathbb{F}_{1^\ell}, with F1\mathbb{F}_1 denoting the field with one element. Our leading motivation is the "Hiden Points Principle," which shows a huge deviation between the set of rational points as closed points defined over F1\mathbb{F}_{1^\ell}, and the set of rational points defined as morphisms Spec(F1)X\texttt{Spec}(\mathbb{F}_{1^\ell}) \mapsto \mathcal{X}. We also introduce, in the same vein as Kurokawa [13], schemes of F1\mathbb{F}_{1^\ell}-type, and consider their zeta functions.
