Default theories over monadic languages

View publication

Abstract

In this paper we compare the semantical and syntactical definitions of extensions for open default theories. We prove that, over monadic languages, these definitions are equivalent and do not depend on the cardinality of the underlying infinite world. We also show that, under the domain closure assumption, one free variable open default theories are decidable. © 2005 Elsevier B.V. All rights reserved.
