On separative refinement monoids

Huanyin Chen

Hangzhou Normal University

Abstract

We obtain two new characterizations of separativity of refinement monoids, in terms of comparability-type conditions. As applications, we get several equivalent conditions of separativity for exchange ideals.

Keywords: refinement monoid, separativity, exchange ideal
