| 소개 및 안내사항Content | Title : Group theoretic understanding of manifold diffeomorphism groups Speaker : Sang-hyun Kim (KIAS) Abstract : Given a smooth manifold M equipped with a geometric or analytic structure $\Omega$, the collection of $\Omega$--preserving diffeomorphisms of M naturally form a group denoted as $Diff^r(M,\Omega)$. These groups often exhibit strong rigidity phenomena, even when treated purely as algebraic objects. In this talk, I will focus on two aspects of these groups along this line. (1) The isomorphism types of finitely generated subgroups. (2) The set of true first-order group--theoretical sentences. This talk is based on joint works with Thomas Koberda (UVa) and with Javier de la Nuez-Gonzalez (KIAS) |
