Mixing for infinite measure preserving systems.Dalia Terhesiu (Roma Tor Vergata)
While the notion of mixing for probability measure preserving systems is
well understood, there exist no definition of mixing that applies to
general infinite measure preserving systems. We will talk about recent
results on the asymptotic behaviour of the transfer operator associated
with a large class of infinite measure preserving systems (including
interval maps with indifferent fixed points). In this sense we provide a
satisfactory definition of mixing for a large class of infinite measure
preserving systems.
