There will be two additional contributed talks, to be announced later.
Konstantin Schäfer (Universität Bremen) An adapted version of Lin's criterion for exactness
Lin's Criterion characterizes exactness (exactness gives ergodicity) of a dynamical system using the transfer operator and integrable functions. Under a few additional conditions, we will be able to improve Lin's criterion such that only a subspace of the integrable functions is needed for the characterization. In particular, we will have a look at concave, strictly increasing functions and discuss an alternate proof for the exactness of the Farey map.
