요약This thesis presents results on various aspects of the spectral theory for hyperbolic differ-entiable dynamical systems.Let M be a smooth manifold and exp(tX) be a uniformly hyperbolic flow with nonwandering set K (see Chapter 2 for definitions), where X is the generator of the flow. The resolvent is defined by(A-X)-:=() dt: C(M)+2(M), Rex 1. (0.0.1)It has a meromorphic extension to AEC as operators C (M)→(M) under suitable assumptions. The set of poles is a discrete subset of C (with multiplicities) called Pollicott-Ruelle resonances and denoted Res(X).This theory was introduced by Pollicott [Pol85] and Ruelle [RueS6, Rue87]. Recently, there have been many developments including the theory of anisotropic Sobolev spaces stud-ied by Baladi-Tsujii [BT07], Blank-Keller-Liverani [BKL02], Butterley-Liverani (BL07], Gouezel-Liverani [GL06], and Liverani [Liv04, Liv05]), and the microlocal theory pioneered by Faure Sjostrand [FS11] and Dyatlov-Zworski [DZ166].Resonances are related to various important aspects of dynamical systems:1. Exponential mixing.Let a be an invariant probability measure on M. The flow is mixing with respect to u if for any f(z).g(2) ∈ C(X), f(x))g(z)dp(x)→ f(x)dp f(x)dp g(x)du, tx. MIt is an important problem in dynamical systems to determine the mixing rate. If for some C. 3,r 0,then we say the mixing rate is exponential. The rate of mixing is closely related to the poles of the resolvent (0.0.1). More precisely, in good circumstances, we have the following asymptotic expansion for f.g C (M): -(2)(2)da ~ ΣΣ(1)(9) ABX) (0.0.2)where (M) are generalized eigenfunctions of the vector field X and its adjoint in certain weighted Sobolev spaces with anisotopic regularities, called resonant states. This gives a very accurate description of the long time behavior of the flow. In particular, exponential mixing corresponds to the existence of a spectral gap, ie. there is some 0 such that all the resonances except 0 has real part less than -(say, in the case when 0 is the first resonance).2. Dynamical zeta function.Let P be the set of primitive closed orbits of the Ruelle zeta function is given by ((*) = Π (1--) TEP (0.0.3)for Res 1 where ((7) is the period of y. In good circumstances, one can show (R(8) has a meromorphic continuation to s EC, and the zeros or poles of ((s) are given by poles of the resolvent on certain vector bundles. This is a natural generalization of the famous Selberg zeta function to nonhomogeneous spaces, which enjoys interesting properties (see [DZ17]).3. Geometric inverse problems.The microlocal theory of hyperbolic dynamical systems has found important appli cations in geometric inverse problems. One important development is the work of Guillarmon-Lefeuvre [GL19] that shows the local marked length rigidity for Anosov manifolds, We refer to [Lef25] for more details.
