DESCRIPTION:Damaris Schindler (University of Bristol)\nIf the descent theo
 ry\, developed by Colliot-Thelene and Sansuc\, applies then it can reduce 
 the question of understanding whether the Brauer-Manin obstruction it the 
 only one to understanding weak approximation on the resulting descent vari
 eties. In many cases the descent varieties are easier to handle and access
 ible by analytic methods. In this talk we focus on varieties corresponding
  to the representation of a norm form by a product of linear polynomials. 
 We give a small survey on analytic methods which are currently available f
 ocusing on these examples. In the second part of the talk we present joint
  work with A. Skorobogatov and explain how the circle method over number f
 ields can be used to prove weak approximation results for certain systems 
 of linear equations involving norm forms.
