Given a Borel action $G\curvearrowright X$ over a Lebesgue space $X$ we show that if $G\curvearrowright X$ preserves an invariant system of packing regular metrics along a Borel lamination $\mathcal F$, then the ergodic measures preserved by the action are rigid in the sense that the system of conditional measures with respect to the partition $\mathcal F$ are induced by the given invariant metric system or are supported in a countable number of boundaries of balls. The argument we employ does… Expand
Lyapunov stability and the Bernoulli property
This paper addresses, and was motivated by, two open questions concerning the Bernoulli property for partially hyperbolic systems with some controlled behavior along the center direction. We proveExpand
The disintegration of measures with periodic repetitive pattern
In the context of locally constant skew-products over the shift with circle fiber maps we introduce the notion of measures with periodic repetitive pattern, inspired by \cite{GorIlyKleNal:05} andExpand
