报告摘要:This talk investigates the research summarization of logical representations for domains. It is divided into four parts.The first part is an introduction of domain theory, which incorporates the background of domain theory, the fundamental definitions of domain structures, and the role of logic in domain theory.In the second part, the history of the representations of domains in terms of information systems is reviewed. It originated with Scott’s information systems for algebraic bounded complete domains, subsequently developed to Hofmann information systems for continuous bounded complete domains, Spreen and Xu’s information systems for continuous domains, and more information systems for other domains. These results can be seen as syntactic representations for domains.The third part focuses on semantic representations of domains based on complete logical systems, ranging from Abramsky’s domain logics for algebraic bounded complete domains and SFP-domains, over Chen and Jung's domain logic for algebraic L-domains, to our domain logics for Lawson compact algebraic L-domains, continuous L-domains and continuous bounded complete domains.Some topics for further study are given in the fourth part.
