Graphs, $F_{1}$ -schemes and virtual mixed Tate motives

Manuel Merida-Angulo, Koen Thas

In a number of recent works [6, 7] the authors have introduced and studied a functor $F_{k}$ which associates to each loose graph $Γ$ -which is similar to a graph, but wher…

Projective spaces over $F_{1^{ℓ}}$

Koen Thas

In this essay we study various notions of projective space (and other schemes) over $F_{1^{ℓ}}$ , with $F_{1}$ denoting the field with one element. Our leading moti…

The combinatorial-motivic nature of $F_{1}$ -schemes

Koen Thas

We review Deitmar's theory of monoidal schemes to start with, and have a detailed look at the standard examples. It is explained how one can combinatorially study such schemes thro…
