Reconstruction theorem for monoid schemes

Category Theory 2020-09-29 v2 Algebraic Geometry

Abstract

We aim to reconstruct a monoid scheme XX from the category of quasi-coherent sheaves over it. This is much in the vein of Gabriel's original reconstruction theorem. Under some finiteness condition on a monoid schemes XX, we show that the localising subcategories of the topos Qc(X)\mathfrak{Qc}(X) of quasi-coherent sheaves on XX is in a one-to-one correspondence with open subsets of XX, while the elements of XX correspond to the topos points of Qc(X)\mathfrak{Qc}(X). This allows us to reconstruct XX from Qc(X)\mathfrak{Qc}(X).
