The space of finitely generated rings
Abstract
The space of marked commutative rings on n given generators is a compact metrizable space. We compute the Cantor-Bendixson rank of any member of this space. For instance, the Cantor-Bendixson rank of the free commutative ring on n generators is omegan, where omega is the smallest infinite ordinal. More generally, we work in the space of finitely generated modules over a given commutative ring.
