The complexity of description logics with concrete domains
Concrete domains are an extension of Description Logics (DLs) that allows to integrate reasoning about conceptual knowledge with reasoning about "concrete qualities" of real world entities such as their age, weight, shape, and temporal extension. In this thesis, we perform an in-depth analysis of …

Complexity results and practical algorithms for logics in knowledge representation
Description Logics (DLs) are used in knowledge-based systems to represent and reason about terminological knowledge of the application domain in a semantically well-defined manner. In this thesis, we establish a number of novel complexity results and give practical algorithms for expressive DLs …

SAT encodings: from constraint based termination analysis to circuit synthesis
Termination is one of the most prominent undecidable problems in computer science. At the same time, the problem whether a given program terminates for all inputs is sufficiently important for the area of program verification to spur decades-long efforts in developing sufficient criteria for …

On games and logics over dynamically changing structures
In the classical framework of graph algorithms, program logics, and corresponding model checking games, one considers changes of system states and movements of agents within a system, but the underlying graph or structure is assumed to be static. This limitation motivates a more general approach …
