Higher-order recursion schemes are equations defining recursively new operations from given ones called “terminals”. Every such recursion scheme is proved to have a least inte...

We study syntax-free models for name-passing processes. For interleaving semantics, we identify the indexing structure required of an early labelled transition system to support t...
The need for integration of ontologies with nonmonotonic rules has been gaining importance in a number of areas, such as the Semantic Web. A number of researchers addressed this p...
