Abstract

We study commutative rings R for which all projective schemes over R have finite morphisms to a projective space of R. We then use our results to define a new kind of capacity for adelic subsets of projective flat schemes X over global fields. This capacity can be used to generalize the converse part of the Fekete–Szegő Theorem.
