DESCRIPTION:A way to study rational points on a variety is by looking at t
 heir image in the p-adic points. Some natural questions that arise are the
  following: is there any obstruction to weak approximation on the variety?
  Which primes might be involved in it? I will explain how primes of good r
 eduction can play a role in the Brauer-Manin obstruction to weak approxima
 tion\, with particular emphasis on the case of K3 surfaces.
