Lecture in Winter Term 2013/14
|V2||Mon 13:00–14:30, Seminar Room i7 ( R 4116 )||Thomas|

The start is on October 14, 13:00-14:00h.
This course is addressed to MSc students. It offers a deeper understanding of the two essential language classes that are fundamental in many areas of computer science: the regular and the context-free languages. Although some of the presented results are quite old, they have not lost their significance. Also some of the oldest open problems of theoretical computer science belong to this area.
Applications will be mentioned, but the emphasis is on theory, with two main topics: alternative descriptions of languages in different frameworks, and classification of languages in terms various views of "complexity".
The course will be given in German if all participants prefer this.
