DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GaTO/122/">C
 urtains\, walls\, and stable cylinders</a>\nby Davide Spriano (Warwick) as
  part of Geometry and topology online\n\nLecture held in Room B3.02 in the
  Zeeman Building\, University of Warwick.\n\nAbstract\nIn this talk we wil
 l discuss a generalization of Sageev’s wallspace construction that allow
 s to study the geometry of certain spaces by combinatorial properties of c
 ertain walls. Specifically\, we’ll look at the interactions with hyperbo
 licity and focus on two applications. In CAT(0) spaces\, these techniques 
 allow to construct a “universal hyperbolic quotient”\, called the curt
 ain model\, that is analogous to the curve graph of a surface. When focusi
 ng on a space that is already hyperbolic\, the construction can be used to
  improve its fine properties\, and in particular we address a conjecture o
 f Rips and Sela and show that residually finite hyperbolic groups admit gl
 obally stable cylinders. \n\nThis is joint work with Petyt and Zalloum.\n
