The equality of the Patch topology and the Ultrafilter topology: A shortcut

Luz M. Ruza, Jorge Vielma


In this work R denotes a commutative ring with non-zero identity andwe prove that the patch topology and the ultrafilter topology definedon the prime spectrum of R are equal, in a different way as the givenby Marco Fontana and K. Alan Loper
