### Project description (pdf-file)

Kirschenhofer's main interests in Discrete Mathematics are Combinatorics (enumeration problems and ``bijective'' proofs, generating functions, combinatorial identities), combinatorial questions in number theory (combinatorial problems leading to Diophantine equations), Diophantine equations (polynomial Diophantine equations, relative Thue equations) and analysis of algorithms. He is a co-researcher of a project within the FWF-NFN S96 and therefore integrated within the corresponding network of research.
