DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UAANTS/5/">N
 on-Abelian Orbifold Theory</a>\nby Thomas Gemuenden (ETH Zurich) as part o
 f University of Arizona Algebra and Number Theory Seminar\n\n\nAbstract\nI
 n this talk\, we will discuss the theory of holomorphic extensions of non-
 abelian orbifold vertex operator algebras. We will give a brief overview o
 f the concepts and motivations of vertex operator algebras and their modul
 es. Then we will construct the module category of non-abelian orbifold ver
 tex operator algebras and classify their holomorphic extensions. If time p
 ermits we will prove that there exist holomorphic vertex operator algebras
  at central charge 72 that cannot be constructed as a holomorphic extensio
 n of a cyclic orbifold of a lattice vertex operator algebra.\n
