Conditions required for the orbit of a set of positive measure to cover state space?

Suppose $(X, \mathcal{M}, \mu, T)$ is a measure-preserving dynamical system with $T$ invertible. I am wondering what properties the dynamical system would need to have in order for the following to be …

Recurrence results for an "on average" measure preserving transformation

I have a finite measure space $(X, \mathcal{S}, \mu)$, and a transformation $f:X\rightarrow X$ that "preserves measure on average". That is, for $A \in \mathcal{S}$ $$ \lim_{n\rightarrow \infty} \fra …
