The intended learning outcome of this course is to understand the contents of the course. Among other effects, this understanding forms the basis for the capability to correctly reproduce the statements and notions covered in the course as well as for the ability to explain and apply the proof techniques used in the course.

The lecture starts with an introduction to the theory of finite automata and formal languages. We get to know the classes of regular and context-free languages, as well as various formalisms for defining such languages, in particular finite automata and formal grammars. In the second part, after a significant leap in expressivity, we will deal with computability theory, i.e., the question which functions are computable in principle. We use the operator representation of partial recursive functions as well as Turing-machines. We discuss the Church-Turing thesis and prove the foundational results of computability theory. In the third part we consider computational complexity theory which is obtained from computability theory by restricting the resources which are available to a computation, e.g. to polynomial time. The P vs. NP -problem belongs to this subject and will form the centre of our discussion of computational complexity.
