Let R be a commutative ring and let Spec R denote the collection of prime ideals of R. We define a topology on Spec R by using ultrafilters and demonstrate that this topology is identical to the well-known patch or constructible topology. The proof is accomplished by use of a von Neumann regular ring canonically associated with R.

Abstract
Let R be a commutative ring and let Spec R denote the collection of prime ideals of R. We define a topology on Spec R by using ultrafilters and demonstrate that this topology is identical to the well-known patch or constructible topology. The proof is accomplished by use of a von Neumann regular ring canonically associated with R.File in questo prodotto:
