Abstract. It is well known that modelchecking and satisfiability of Linear Temporal Logic (LTL) are Pspace-complete. Wolper showed that with grammar operators, this result can be e...
One important class of spatial database queries is the class of topological queries, that is, queries invariant under homeomorphisms. Westudy topological queries expressible in th...
We consider logical expressions built on the single binary connector of implication and a finite number of literals (boolean variables and their negations). We prove that asympto...
Hierarchical graph definitions allow a modular description of graphs using modules for the specification of repeated substructures. Beside this modularity, hierarchical graph de...
Motivated by the need to extend features of semantic matchmaking between request and offer descriptions, a model is presented that exploits recently proposed non-standard inference...
