Harald Fripertinger

Harald Fripertinger is a part-time lecturer at the University of Graz, affiliated with the Department of Mathematics and Scientific Computing. His academic work spans functional equations, iteration theory, coding theory, and mathematical music theory.

• Teaches courses like Codierung und Kryptographie (VU 3st.) and Forschungsseminar aus Funktionalgleichungen und Iterationstheorie II (2st.).
• Develops and maintains the SYMMETRICA computer algebra system for combinatorial and group-theoretic computations.

Research interests include:

• Functional equations and iteration theory, focusing on formal power series and Lie-Gröbner series.
• Coding theory, particularly error-correcting linear codes and their classification.
• Mathematical music theory, analyzing tone rows, tropes, and tiling problems in music.
• Combinatorics under group actions, with applications to finite structures and enumeration.

Projects involve symmetry classes of mappings, cycle indices for linear groups, and computational methods in algebraic combinatorics.
