摘要: Following the vision of Newhouse, we show that smooth surface dynamics in positive entropy exhibit many of the properties of uniform hyperbolicity. We present a new property, which we call Strong Positive Recurrence. It is satisfied by all $C^\infty$ surface diffeomorphisms with positive topological entropy and implies many properties for the measures maximizing the entropy such as: finiteness, exponential mixing, almost sure invariance principle, etc.
