Call for Papers 39th International Symposium on Mathematical Foundations of Computer Science MFCS 2014 Budapest, August 25--29, 2014 www.inf.u-szeged.hu/mfcs2014 *Announcement* The series of MFCS symposia, organized since 1972, has a long and well-established tradition. The MFCS conferences encourage high-quality research in all branches of theoretical computer science. Their broad scope provides an opportunity to bring together researchers who do not usually meet at specialized conferences. Quality papers presenting original research on theoretical aspects of computer science are solicited. *Topics* Principal topics of interest include (but are not limited to): algorithms and data structures (incl. sequential, parallel, distributed, randomized, approximation, graph, network, on-line, parameterized, optimization algorithms), algorithmic game theory, algorithmic learning theory, computational complexity (structural and model-related), computational geometry, models of computation, networks (incl. wireless, sensor, ad-hoc networks), parallel and distributed computing, quantum computing, automata, grammars and formal languages, combinatorics on words, trees, and other structures, bioinformatics, computer-assisted reasoning, concurrency theory, cryptography and security, databases and knowledge-based systems, formal specifications and program development, foundations of computing, logic, algebra and categories in computer science, types in computer science, mobile computing, semantics and verification of programs, theoretical issues in artificial intelligence. *Invited Speakers* Krishnendu Chatterjee (IST Austria, Klosterneuburg, Austria), Achim Jung (U. of Birmingham, UK), D\'aniel Marx (Hungarian Academy of Sciences, Budapest, Hungary), Peter Bro Miltersen (Aarhus U., Denmark), Cyril Nicaud (U.
