NP-Completeness of Refutability by Literal-Once Resolution
A boolean formula in conjunctive normal form (CNF) F is refuted by literal?once resolution if the empty clause is inferred from F by resolving on each literal of F at most once. Li...

Approximating Dependency Graphs Using Tree Automata Techniques
The dependency pair method of Arts and Giesl is the most powerful technique for proving termination of term rewrite systems automatically. We show that the method can be improved b...

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...

A Sequent Calculus for First-Order Dynamic Logic with Trace Modalities
The modalities of Dynamic Logic refer to the final state of a program execution and allow to specify programs with pre- and postconditions. In this paper, we extend Dynamic Logic w...
