Using Tropical Degenerations For Proving The Nonexistence Of Certain Nets
Tropical Degenerations The Nonexistence Of Certain Nets Algebraic Geometry
2011/9/22
Abstract: A net is a special configuration of lines and points in the projective plane. There are certain restrictions on the number of its lines and points. We proved that there cannot be any (4,4) n...
Construction of schemes over $F_1$, and over idempotent rings: towards tropical geometry
$F_1$ over idempotent rings towards tropical geometry

In this paper, we give some categorical description of the general spectrum functor, defining it as an adjoint of a global section functor.The general spectrum functor includes that of F1 and of semir...
