My research in the area of Theoretical Computer Science at the Open University
of Hagen in the 1980s focused on the theoretical investigation of the
computability and computational complexity of operations on noncountable
domains such as real numbers of function spaces. The underlying Type2
computability model was based on a variation of OracleTuring machines,
while representations (an extension of the concept of numberings) were used to
transfer computability concepts to arbitrary domains.

Most of my publications in the area of
Theoretical Computer Science were written with a typewriter and are not
available online. However, an abstract with a complete reference and
corresponding bibtex entry is provided and I can send you a hard copy if
you send an email to . Note that my
Master Thesis (Diplomarbeit) and PhD Thesis were written in German.
A list of related web pages is given to simplify cross references.
