# Seminar: Automata Theory

Summer Term 2014

## Content

Subject of this seminar are original works and overview articles concerning automata theory, usually with emphasis in the vicinity of the lecture Infinite Computations (the topics will be depending on the knowlege of the participant altered to accommodate Angewandte Automatentheorie). Active participation of this lecture (or similar lectures in previous terms) including the exercises are helpful in handling the topics and will be considered when apointing the slots.

It is a seminar of theoretical computer science. It will be required that the students know how to handle abstract models and mathematical proof.

For an idea of possible topics some web sites of previous terms can be found in the Archiv.

## Organization

- General information can be found at slides of the introduction (german only).
- As a result of the large attendance this seminar won't be held weekly but on a few dates as a block course at the end of the semester.
- The following dates have to be remembered appart from the date of presentation:
- The first talk with your supervisor before the 17.4.2014
- due date: a maximum of three weeks before the presentation
