Research Group Theory of Computability over Algebraic Structures
The Theory of Computability over Algebraic Structures is essentially a branch of mathematical logic which is related to theoretical computer science. It deals with different models of computation, where operations of algebraic structures are permitted, and includes generalizations of the classic recursion theory.

Topics for Bachelor, Master and PhD thesis
If you are interested in writing a thesis in any of the following topics, please contact: firstname.lastname@example.org.
- The power of models of computation between finite automata and BSS-RAM's over algebraic structures. This topic was proposed at a working meeting 2014. The aim is to collect application examples and to compare different types of automata as well as to prove the power of individual types of automata and the insolubility of problems by certain automata.

- The significance of the axioms of choice
