Abstract：Motivated by results of Thurston, we prove that any autoequivalence on a triangulated category induces a canonical filtration by triangulated subcategories, provided the existence of Bridgeland stability conditions. We then propose a new definition of pseudo-Anosov autoequivalences, and prove that our definition is more general than the one previously proposed by Dimitrov-Haiden-Katzarkov-Kontsevich. We construct new examples of pseudo-Anosov autoequivalences on the derived categories of quintic Calabi-Yau threefolds and quiver Calabi-Yau categories. This is a joint work with Filip, Haiden, Katzarkov, and Liu.
