Wednesday 18 Oct 2017. 16:30--18:00
Title : Symmetry of mapping classes, quadratic differentials and outer automorphisms
Speaker : Hidetoshi Masai (Mathematical Science Group at AIMR, Tohoku University)
Room : A-427, Faculty of Science, Shinshu University
Abstract : We mainly consider notion called fibered commensurability, which allows us to study symmetry of maps. Fibered commensurability is first defined by Calegari-Sun-Wang on mapping classes group. We first recall known facts of fibered commensurability of mapping classes. In the course, we observe that commensurability of quadratic differentials is related to fibered commensurability. Then we discuss analogy for outer automorphism groups of free groups. A part of this talk is based on the joint work with Ryosuke Mineyama.
