Project description (pdf-file)

The proposer of this project has been interested in the analysis and probability on fractals since the early 1990s. He has written several publications on this subject, as well as supervised three related PhD-theses. He is especially interested in the application of generating function techniques to this subject, which gives a close relation to the iteration theory of rational functions. Furthermore, the proposer has contributed to the study of digital expansions and their probabilistic and ergodic properties. Especially, he is interested in the study of distribution properties of arithmetic functions related to digital expansions, such as additive and multiplicative functions and representation numbers for redundant numeration, application of techniques from ergodic theory and probability theory to the study of systems of numeration, and applications of redundant numeration to cryptography.
