Attracting measures
Under mild assumptions, the SRB measure $μ$ associated to an Axiom A attractor $A$ has the following properties: (i) the empirical measure starting at a typical point near $A$ converges weakly to $μ$; (ii) the pushforward of any Lebesgue-absolutely continuous probability measure supported near $A$ converges weakly to $μ$. In general, a measure with the first property is called a "physical measure", and physical measures are recognised as generally important in their own right. In this paper,…
