Inverse Roles Make Conjunctive Queries Hard
Abstract. Conjunctive query answering is an important DL reasoning task. Although this task is by now quite well-understood, tight complexity bounds for conjunctive query answering...

Automating the Dependency Pair Method
Developing automatable methods for proving termination of term rewrite systems that resist traditional techniques based on simplification orders has become an active research area ...

Automated Incremental Termination Proofs for Hierarchically Defined Term Rewriting Systems
We propose the notion of rewriting modules in order to provide a structural and hierarchical approach of TRS. We define then relative dependency pairs built upon these modules whic...

Automated Complexity Analysis Based on the Dependency Pair Method
In this paper, we present a variant of the dependency pair method for analysing runtime complexities of term rewrite systems automatically. This method is easy to implement, but si...

System for Automated Deduction (SAD): A Tool for Proof Verification
In this paper, a proof assistant, called SAD, is presented. SAD deals with mathematical texts that are formalized in the ForTheL language (brief description of which is also given)...
