DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GaTO/76/">Co
 mbinatorial criteria for hyperbolicity</a>\nby Davide Spriano (Oxford) as 
 part of Geometry and topology online\n\nLecture held in Room B3.02 in the 
 Zeeman Building\, University of Warwick.\n\nAbstract\nPerhaps one of the m
 ost fascinating properties of hyperbolic groups is that they admit equival
 ent definitions coming from different areas of mathematics. In this talk\,
  we will survey some interesting definitions\, and discuss a new one that\
 , perhaps surprisingly\, was previously unknown\, namely that fact that hy
 perbolicity can be detected by the language of quasi-geodesics in the Cayl
 ey graph. As an application\, we will discuss some progress towards a conj
 ecture of Shapiro concerning groups with uniquely geodesic Cayley graphs.\
