In this reading group, we now study the article "Ruelle spectrum of linear pseudo-Anosov maps" by F. Faure, S. Gouëzel et E. Lanneau. Its goal is to make explicit the structure of Ruelle resonances of linear pseudo-Anosov maps.

In this third session, we finish the study of the distribution spaces appearing in this construction, and document some properties of the spectrum of the Koopman operator.
