This Festschrift has been put together on the occasion of Franz Baader's 60th birthday to celebrate his fundamental and highly influential scientific contributions. The 30 papers in this volume cover several scientific areas that Franz Baader has been working on during the last three decades, including description logics, term rewriting, and the combination of decision procedures. We hope that readers will enjoy the articles gathered in Franz's honour and appreciate the breadth and depth of his favourite areas of computer science.

This book constitutes the refereed proceedings of the 19th International Symposium on Fundamentals of Computation Theory, FCT 2013, held in Liverpool, UK, in August 2013. The 29 papers (26 full papers and 3 invited papers) were carefully reviewed and selected from 58 submissions. The papers cover the following topics: algorithms, formal methods, and emerging fields.

This book constitutes the refereed proceedings of the 6th International Symposium on Frontiers of Combining Systems, FroCoS 2007, held in Liverpool, UK, September 10-12, 2007.

The 14 revised full papers presented were carefully reviewed and selected. The papers are organized in topical sections on combinations of logics, theories, and decision procedures; constraint solving and programming; combination issues in rewriting and programming as well as in logical frameworks and theorem proving systems.

Advances in Modal Logic is a unique forum for presenting the latest results and new directions of research in modal logic broadly conceived. The topics dealt with are of interdisciplinary interest and range from mathematical, computational, and philosophical problems to applications in knowledge representation and formal linguistics.

Volume 3 presents substantial advance in the relational model theory and the algorithmic treatment of modal logics. It contains invited and contributed papers from the third conference on "Advances in Modal Logic," held at the University of Leipzig (Germany) in October 2000. It includes papers on dynamic logic, description logics, hybrid logics, epistemic logics, combinations of modal logics, tense logic, action logic, provability logic, and modal predicate logic.
