Computer science description: We study may and must testing-based preorders in an asynchronous setting. In particular, we provide some full abstraction theorems that offer alternative characterizations of these preorders in terms of context closure w.r.t. basic observables and in terms of traces and acceptance sets. These characterizations throw light on the asymmetry between input and output actions in asynchronous interactions and on the difference between synchrony and asynchrony. publisher: Springer contributor: Nivat, Maurice date: 1998 type: Book Section type: PeerReviewed identifier: Boreale, Michele and De Nicola, Rocco and Pugliese, Rosario Asynchronous Observations of Processes.
