Abstract. The little theories method, in which mathematical reasoning is distributed across a network of theories, is a powerful technique for describing and analyzing complex syst...
We extend the theory about terminological default reasoning by using a logical base language that can represent spatioterminological phenomena. Based on this description logic lang...
In this article we extend previous work on the development of logical foundations for the specification of the dynamics of databases. In particular, we deal with two problems. Fir...
