Cosmological lower bound on the circuit complexity of a small problem in logic
An exponential lower bound on the circuit complexity of deciding the weak monadic second-order theory of one successor (WS1S) is proved. Circuits are built from binary operations, ...

Complexity of Axiom Pinpointing in the DL-Lite Family of Description Logics
We investigate the complexity of axiom pinpointing for different members of the DL-Lite family of Description Logics. More precisely, we consider the problem of enumerating all mi...

Inter-process buffers in separation logic with rely-guarantee
Separation logic allows simple proofs of concurrent algorithms which use blocking mechanisms such as semaphores. It can even deal with non-blocking algorithms. With the addition of...

Fixpoint Logics over Hierarchical Structures
Hierarchical graph definitions allow a modular description of graphs using modules for the specification of repeated substructures. Beside this modularity, hierarchical graph de...

Addressing the Timing Closure Problem by Integrating Logic Optimization and Placement
Timing closure problems occur when timing estimates computed during logic synthesis do not match with timing estimates computed from the layout of the circuit. In such a situation...
