SUMMARY:String theory\, T-duality and non-geometry - Chris Blair (Universi
 ty of Cambridge)

DESCRIPTION:A remarkable feature of string theory is the existence of powe
 rful and unexpected duality symmetries. One such is T-duality\, which in i
 ts simplest form relates a string wrapped around a large circle to a strin
 g moving on a small circle. In this talk\, I will give an introduction to 
 T-duality\, and explain how one can define so-called `non-geometric' backg
 rounds\, which are only globally defined if one allows patching by duality
  transformations in addition to the usual geometric coordinate and gauge t
 ransformations. No prior exposure to string theory will be assumed.
