Elementary divisors, Hochster duality, and spectra

  • Wolfgang Rump

摘要

It is proved that every Bézout domain admits an embedding into an elementary divisor domain with the same divisibility group. So the prime spectrum of a Bézout domain is homeomorphic to the prime spectrum of an elementary divisor domain. Together with an earlier result, it follows that a topological space is homeomorphic to the maximal spectrum of an elementary divisor domain if and only if it is a serial quasi-compact \(T_1\) T 1 -space.
