A crash introduction to Infinite Ergodic Theory with a view on
the question of Infinite Mixing
In the first part of the talk I will give a super concise introduction
to Infinite Ergodic Theory, discussing about what happens to the
standard properties of recurrence, ergodicity and mixing when we
consider dynamical systems preserving an infinite measure. In the
second part I will illustrate my my point of view on the debated
question of mixing in infinite ergodic theory (infinite mixing).
Finally, if time permits, I will show recent results about the
infinite-mixing properties of certain popular maps.
