Michal Misiurewicz



  • 1971  MS, University of Warsaw, Warsaw, Poland
  • 1974  PhD, University of Warsaw, Warsaw, Poland


My major research activities are in Dynamical Systems and Ergodic Theory. Those areas of Mathematics are about the evolution of various systems in time, from the differential, topological and statistical points of view. Main objects of interest in my research are one-dimensional systems, entropy, periodic orbits and connections with other parts of Mathematics and other sciences, including applications of Dynamical Systems.

One-dimensional systems are especially interesting, since they display many features of more general systems, while it is possible to apply special tools for their investigation. My proofs of existence of an absolutely continuous measure (which means that the system is chaotic, but can be successfully studied from the statistical points of view) were acknowledged in names like "Misiurewicz maps" in real dynamics and "Misiurewicz points" in complex dynamics.

Another interesting aspect of one-dimensional dynamics studied by me is relation between periodic orbits of various periods and relation between those orbits and the measure of chaos, topological entropy. This constitutes a new area of Dynamical Systems, Combinatorial Dynamics. A book I wrote with my collaborators from Barcelona, Spain, is an important resource in this area.

Following current trends, I study random dynamical systems, including quasiperiodically forced ones, and connections with other branches of Mathematics, for instance Braid Theory and Game Theory. I also apply my expertise to systems arising in various sciences, like Economics and Mathematical Biology. In particular, together with my colleagues from the Department of Mathematical Sciences and economists from IUPUI and IU Bloomington, I study models of so called Nash maps, coming from Economics.
