%0 Journal Article %T Contact Anosov flows and the FBI transform %A Masato Tsujii %J Mathematics %D 2010 %I arXiv %X This paper is about spectral properties of transfer operators for contact Anosov flows. The main result gives the essential spectral radius of the transfer operators acting on the so-called anisotropic Sobolev space exactly in terms of dynamical exponents. Also we provide a simplified proof by using the FBI transform. %U http://arxiv.org/abs/1010.0396v3
