研究了2环面上双曲型线性自同构的实解析摄动。当作用于合适的希尔伯特空间时,库普曼算子和传递算子是0阶核算子。我们证明了这两个算子的非平凡Ruelle共振的一般存在性。我们证明了一些扰动保持了体积,而另一些则没有。
We study real analytic perturbations of hyperbolic linear automorphisms on the 2-torus. The Koopman and the transfer operator are nuclear of order 0 when acting on a suitable Hilbert space. We show the generic existence of non-trivial Ruelle resonances for both operators. We prove that some of the perturbations preserve the volume and some of them do not.
