If the descent theory, 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 varieties. In many cases the descent varieties are easier to handle and accessible 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 focusing 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 fields can be used to prove weak approximation results for certain systems of linear equations involving norm forms.
