DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AGSAGS/26/">
 On the interaction of normal square-tiled surfaces and group theory</a>\nb
 y Andrea Thevis (Aachen University) as part of American Graduate Student A
 lgebraic Geometry Seminar\n\n\nAbstract\nA translation surface is obtained
  by taking finitely many polygons in the Euclidean plane and gluing them a
 long their edges by translations. If we restrict to gluing unit squares\, 
 we obtain a square-tiled surface\, also known as origami. In the first par
 t of the talk\, I explain some motivations for studying translation surfac
 es. I especially aim to point out why it is natural to study square-tiled 
 surfaces in some of these contexts. In the second part of the talk\, we co
 nsider certain square-tiled surfaces with maximal symmetry group in more d
 etail. More precisely\, we examine their types of singularities and their 
 Veech groups using group theoretic methods. This is partially joint work w
 ith Johannes Flake.\n
