Abstract
Dynamical zeta functions are meromorphic functions associated with a dynamical system through its closed orbits, typically via Euler products or Poincaré series. Although they are defined in purely dynamical terms, they often encode remarkably rich geometric and topological information. In this talk, I will present several results illustrating how special values of dynamical zeta functions recover subtle topological invariants of the underlying space such that the Euler characteristic or the Reidemeister torsion.
About Pure mathematics seminars
We present regular seminars on a range of pure mathematics interests. Students, staff and visitors to UQ are welcome to attend, and to suggest speakers and topics.
Seminars are usually held on Tuesdays from 2 to 3pm.
Talks comprise 45 minutes of speaking time plus five minutes for questions and discussion.
Information for speakers
Researchers in all pure mathematics fields attend our seminars, so please aim your presentation at a general mathematical audience.
