我们考虑由实数和 p 进李群的乘积定义的齐次空间上的部分双曲、半简单、高阶动作的不变测度。在本文中,我们概括了我们早期的工作,以在该设置下的高熵情况下建立测量刚性。我们避免任何额外的遍历类型假设,而是依赖并扩展条件测度理论。
We consider invariant measures for partially hyperbolic, semisimple, higher rank actions on homogeneous spaces defined by products of real andp-adic Lie groups. In this paper we generalize our earlier work to establish measure rigidity in the high entropy case in that setting. We avoid any additional ergodicity-type assumptions but rely on, and extend the theory of conditional measures.
