Abstract
We give a simplified treatment of decay of correlations for nonuniformly
expanding systems, combining operator renewal theory with dynamical
truncation. In addition to being simplified, the method is also more
flexible, applying to general return time functions and requiring weaker
conditions on transfer operators than is customary. This is joint work with
Dalia Terhesiu.
