AI 中文摘要
我们证明了双曲流形上标架流生成元在远离共振竖直线时的预解估计。该证明的一个推论是生成元的最优本质谱隙性质,由此给出标架流关于标架丛体积测度指数混合的另一证明。这将文献[arXiv:2005.08387v2]的3维结果推广到任意维数,我们大量使用文献[arXiv:2405.14846]发展的Borel-Weil演算来克服高维情形的困难。
英文摘要
We prove a resolvent estimate for the generator of the frame flow on hyperbolic manifolds away from vertical lines of resonances. A byproduct of the proof is an optimal essential spectral gap property for the generator, hence giving another proof of exponential mixing of frame flows with respect to the volume measure of the frame bundle. This extends the result of [https://arxiv.org/abs/2005.08387v2] in dimension 3 to any dimension. We make extensive use of the Borel-Weil calculus developed in [https://arxiv.org/abs/2405.14846] to overcome difficulties of this higher-dimensional case.
